The maintaining of an optimal pH is essential to maximise optimum growth. The general rule of thumb is that as pH increases the solubility of minerals and nutrients decrease. It is important that nutrients are soluble for plants to uptake and use for growth. The pH of nutrient solution can also affect the bacteria that fix nitrogen for the plant to use. Every plant has optimum pH levels for growth. Below is a table for the ideal pH range for a variety of plants.\u003c\/p\u003e\n\u003cp\u003eThe Hanna Instruments-98118 can be used to measure the pH in soils as well as nutrient solutions. To measure the pH of soil as a slurry it is recommended to use a mixture of 1 part soil to 1 part water. The slurry is allowed to rest for 10 minutes so that the solids will settle out and the pH of liquid above can be measured.\u003c\/p\u003e\n\u003cp\u003eThe Hanna Instruments-98118 is an advanced meter while maintaining simplicity. The front of the meter has two buttons. One is for turning the meter on and off while the other is used to enter the calibration mode.

Customisation includes temperature readout in °C or °F, automatic shut off selectable from 8 minutes, 60 minutes or disabled, and lastly the choice of using Hanna's Quick Cal pH\/EC standard or traditional buffers values of pH 4.01, 7.01 and 10.01.\u003c\/p\u003e\n\u003cp\u003eThe electrode features a unique extractable cloth junction. The reference junction of a pH electrode, also known as a salt bridge, provides an electrical pathway between the internal reference cell and the sample. Any clogging of the junction will result in a disruption of the electrical pathway. When this happens the readings will be erratic and take a very long time to stabilise. With the Hanna extractable junction a small portion of 1\/8\" is extracted or pulled to expose a clean surface. With the junction renewed the clogging is cleared allowing the meter to still be used.

The nutrient concentration in the water used for irrigation is critical for the successful propagation and growth of plants.\u003c\/p\u003e\u003ch3\u003eHI-981413-00 GroLine EC\/TDS\/Temp Nutrient dosing system with HI-30033 conductivity probe\u003c\/h3\u003e \u003cp\u003eThe HI-981413 uses an amperometric conductivity sensor for measuring the amount of fertiliser in the solution. The meter can be programmed to display results as EC (electrical conductivity) or as TDS (total dissolved solids). The EC results are displayed as mS\/cm while TDS is displayed as ppm with a selectable conversion factor from 0.45 to 0.99.\u003c\/p\u003e \u003cp\u003eThe HI-981413 was developed to be an inexpensive solution for the horticulturist to maintain the ideal fertiliser concentrations at all times. Simply insert the probe and injection valve in-line with the recirculation pump and provide the chemical to be dosed.\u003c\/p\u003e \u003ch3\u003eHI-30033 EC\/Temperature Probe\u003c\/h3\u003e \u003cp\u003eThe HI-981413 uses the HI-30033 probe that incorporates both EC (TDS) and temperature sensors and connects to the controller with a single waterproof Quick Connect DIN connector. The PVDF body of the probe has a 1\/2” threaded fitting for insertion to an in-line “T” fitting or the flow cell. The back end part of the probe has 3\/4” NPT threads for submersion\/tank mounting. The probe body has a hex fitting for tightening snuggly with a wrench.\u003c\/p\u003e \u003ch3\u003ePeristaltic Dosing Pump\u003c\/h3\u003e \u003cp\u003eThe HI-981413 has a powerful built-in peristaltic chemical feed pump that utilises a stepper motor which does not have any gears or brushes to wear out. This design provides for a long life and little maintenance.\u003c\/p\u003e \u003ch3\u003eAutomatic Proportional Pump Control\u003c\/h3\u003e \u003cp\u003eThe peristaltic dosing pump can be controlled by simple on\/off or more advanced proportional control which helps prevent overshooting of the set point. When using proportional control the flow rate that is programmed, will be impacted by the proportional band used. The closer the reading is to the set point the longer it takes for the peristaltic pump to complete one revolution. If the reading is outside the proportional band then the amount of time it takes to complete one revolution is based on the flow rate programmed.\u003c\/p\u003e \u003ch3\u003eQuick Connect Probe Input\u003c\/h3\u003e \u003cp\u003eThe Quick Connect DIN connector creates a waterproof seal with the controller making it ideal for reducing electrical noise issues with the connection caused by humid environments.\u003c\/p\u003e \u003cp\u003eFor example, a controller is programmed to have a set point of 1.50 mS\/cm with a 0.30 mS\/cm proportional band and the flow rate at 1 L\/h. Any reading above 1.80 mS\/cm will cause the dosing of acid to be at 1 L\/h. If the reading is at 1.65 mS\/cm, which is 1\/2 of the band, then the dosing pump will run at half speed or deliver 0.5 L\/h of chemical. The closer the reading is to the set point the longer it takes for the pump to complete one rotation. This allows for very fine control of the EC\/TDS value desired.\u003c\/p\u003e \u003ch3\u003eAdjustable Flow Rate\u003c\/h3\u003e \u003cp\u003eThe flow rate from the dosing pumps is adjustable from 0.5 to 3.5L\/h. Larger bodies of water require more chemical to be dosed than smaller ones in per unit of time. The adjustable flow rate, like the proportional band, allows for better control in maintaining a desired set point.\u003c\/p\u003e \u003ch3\u003eNutrient Level\/Flow Switch Input\u003c\/h3\u003e \u003cp\u003eThe HI-981413 allows for a connection to an optional level controller or flow switch. This input can be used to disable the dosing pump when there is no chemical left in the reservoir tank or there is no flow due to the pump being turned off.\u003c\/p\u003e \u003ch3\u003eProgrammable Alarm System\u003c\/h3\u003e \u003cp\u003eEnables or disables the low and high-level alarms for pH. When an alarm is activated, all dosing will stop.

When using proportional control the flow rate that is programmed, will be impacted by the proportional band used. The closer the reading is to the set point the longer it takes for the peristaltic pump to complete one revolution. If the reading is outside the proportional band then the amount of time it takes to complete one revolution is based on the flow rate programmed.\u003c\/p\u003e \u003ch3\u003e\u003c\/h3\u003e \u003ch3\u003eQuick Connect Probe Input\u003c\/h3\u003e \u003cp\u003eThe Quick Connect DIN connector creates a waterproof seal with the controller making it ideal for reducing electrical noise issues with the connection caused by humid environments.\u003c\/p\u003e \u003cp\u003eFor example, a controller is programmed to have a set point of 1.50 mS\/cm with a 0.30 mS\/cm proportional band and the flow rate at 1 L\/h. Any reading above 1.80 mS\/cm will cause the dosing of acid to be at 1 L\/h. If the reading is at 1.65 mS\/cm, which is 1\/2 of the band, then the dosing pump will run at half speed or deliver 0.5 L\/h of chemical. The closer the reading is to the set point the longer it takes for the pump to complete one rotation. This allows for very fine control of the EC\/TDS value desired.\u003c\/p\u003e \u003ch3\u003eAdjustable Flow Rate\u003c\/h3\u003e \u003cp\u003eThe flow rate from the dosing pumps is adjustable from 0.5 to 3.5L\/h. Larger bodies of water require more chemical to be dosed than smaller ones in per unit of time. The adjustable flow rate, like the proportional band, allows for better control in maintaining a desired set point.\u003c\/p\u003e \u003ch3\u003eNutrient Level\/Flow Switch Input\u003c\/h3\u003e \u003cp\u003eThe HI-981413 allows for a connection to an optional level controller or flow switch.

The PVDF body of the probe has a 1\/2” threaded fitting for insertion to an in-line “T” fitting or the flow cell. The back end part of the probe has 3\/4” NPT threads for submersion\/tank mounting. The probe body has a hex fitting for tightening snuggly with a wrench.\u003c\/p\u003e \u003ch3\u003ePeristaltic Dosing Pump\u003c\/h3\u003e \u003cp\u003eThe HI-981413 has a powerful built-in peristaltic chemical feed pump that utilises a stepper motor which does not have any gears or brushes to wear out. This design provides for a long life and little maintenance.\u003c\/p\u003e \u003ch3\u003eAutomatic Proportional Pump Control\u003c\/h3\u003e \u003cp\u003eThe peristaltic dosing pump can be controlled by simple on\/off or more advanced proportional control which helps prevent overshooting of the set point. When using proportional control the flow rate that is programmed, will be impacted by the proportional band used. The closer the reading is to the set point the longer it takes for the peristaltic pump to complete one revolution. If the reading is outside the proportional band then the amount of time it takes to complete one revolution is based on the flow rate programmed.\u003c\/p\u003e \u003ch3\u003eQuick Connect Probe Input\u003c\/h3\u003e \u003cp\u003eThe Quick Connect DIN connector creates a waterproof seal with the controller making it ideal for reducing electrical noise issues with the connection caused by humid environments.\u003c\/p\u003e \u003cp\u003eFor example, a controller is programmed to have a set point of 1.50 mS\/cm with a 0.30 mS\/cm proportional band and the flow rate at 1 L\/h. Any reading above 1.80 mS\/cm will cause the dosing of acid to be at 1 L\/h. If the reading is at 1.65 mS\/cm, which is 1\/2 of the band, then the dosing pump will run at half speed or deliver 0.5 L\/h of chemical. The closer the reading is to the set point the longer it takes for the pump to complete one rotation. This allows for very fine control of the EC\/TDS value desired.\u003c\/p\u003e \u003ch3\u003eAdjustable Flow Rate\u003c\/h3\u003e \u003cp\u003eThe flow rate from the dosing pumps is adjustable from 0.5 to 3.5L\/h. Larger bodies of water require more chemical to be dosed than smaller ones in per unit of time. The adjustable flow rate, like the proportional band, allows for better control in maintaining a desired set point.\u003c\/p\u003e \u003ch3\u003eNutrient Level\/Flow Switch Input\u003c\/h3\u003e \u003cp\u003eThe HI-981413 allows for a connection to an optional level controller or flow switch. This input can be used to disable the dosing pump when there is no chemical left in the reservoir tank or there is no flow due to the pump being turned off.\u003c\/p\u003e \u003ch3\u003eProgrammable Alarm System\u003c\/h3\u003e \u003cp\u003eEnables or disables the low and high-level alarms for pH. When an alarm is activated, all dosing will stop. For added safety, the alarm system also offers overdosing protection in that if the set point value is not corrected within a programmed time interval then the meter will go into alarm status.\u003c\/p\u003e \u003ch3\u003eMulti-coloured LCD Display\u003c\/h3\u003e \u003cp\u003eThe HI-981413 features a multi-coloured LCD that provides for a quick way to see the status of the controller. If in control mode and operating as intended the display will be green.

The pH scale goes from 0 (very acidic) to 14 (basic) with pH 7 being neutral. Soil can be acid, neutral or alkaline.\u003c\/p\u003e \u003cp\u003eMost plants prefer a pH range from 5.5 to 7.5; but some species prefer more acid or alkaline soils. Nevertheless, every plant has a target for optimum growth.\u003c\/p\u003e \u003cp\u003epH strongly influences the availability of nutrients and the presence of micro-organisms and plants in the soil.\u003c\/p\u003e \u003cp\u003eFor example, fungi prefer acidic conditions whereas most bacteria, especially those supplying nutrients to the plants, have a preference for moderately acidic or slightly alkaline soils. In fact, in strongly acidic conditions, nitrogen fixing and the mineralisation of vegetable residual is reduced. Plants absorb the nutrients dissolved in the soil water and the nutrient solubility depends largely on the pH value. Hence, the availability of elements is different at varying pH levels.\u003c\/p\u003e \u003cp\u003eEach plant needs elements in different qualities and this is the reason why each plant requires a particular range of pH to optimise its growth.\u003c\/p\u003e \u003cp\u003eFor example, iron, copper and manganese are not soluble in an alkaline environment. This means that plants needs these elements should theoretically be in an acidic type of soil. Nitrogen, phosphorus, potassium and sulphur, on the other hand, are readily available in a pH range close to neutrality.\u003c\/p\u003e \u003cp\u003eAbnormal pH values may increase the concentration of toxic elements for plants. For example, a plant may not tolerate an excess of aluminium ions that may increase under acidic conditions. When pH values are too far from neutral conditions a less permeable and more compact soil may result.\u003c\/p\u003e \u003cp\u003eDifferent naturally occurring minerals may affect soil pH in the same way.\u003c\/p\u003e \u003ch3\u003eSupplied with:\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eHI-12923 pH\/temperature probe with conical tip, DIN Connector and 1m cable\u003c\/li\u003e \u003cli\u003eHI-70004 pH 4.01 buffer (1 sachet)\u003c\/li\u003e \u003cli\u003eHI-70007 pH 7.01 buffer (1 sachet)\u003c\/li\u003e \u003cli\u003eHI-700663 cleaning solution for soil deposits (1 sachet)\u003c\/li\u003e \u003cli\u003eHI-700664 cleaning solution for humus deposits (1 sachet)\u003c\/li\u003e \u003cli\u003eHI-7051M soil sample preparation solution\u003c\/li\u003e \u003cli\u003eHI-721319 auger for ground penetration, packed separately in a carton box\u003c\/li\u003e \u003cli\u003ebeaker (1)\u003c\/li\u003e \u003cli\u003e1.5 AAA alkaline batteries\u003c\/li\u003e \u003cli\u003eInstrument quality certificate\u003c\/li\u003e \u003cli\u003eElectrode quality certificate\u003c\/li\u003e \u003cli\u003eInstruction manual\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eThe electrode, auger \u0026amp; soil prep solution explained\u003c\/h3\u003e \u003cp\u003eHI-12923 has a conical rugged tip.
