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. There is a third button in the battery compartment that allows the user to customise the meter to their preference. 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 overall length of the junction is about 1\" so the junction should only be extracted periodically.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBuilt in temperature sensor for Automatic Temperature Compensated measurements\u003c\/li\u003e\n\u003cli\u003eRenewable junction to clear any clogging that causes readings to drift and be erratic\u003c\/li\u003e\n\u003cli\u003eStability indicator that disappears once a stable reading is obtained\u003c\/li\u003e\n\u003cli\u003eAutomatic calibration to one or two points at a push of a button\u003c\/li\u003e\n\u003cli\u003eUses Hanna's Quick Cal pH\/EC standard with a pH value of 6.86\u003c\/li\u003e\n\u003cli\u003eBattery % level displayed at start up\u003c\/li\u003e\n\u003cli\u003eLow battery indicator that is displayed when less than 10% battery life is remaining\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":40354422751383,"sku":"HI-98118","price":76.76,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/5511\/6439\/products\/hi98118_default_ed3597fc-a044-4e00-95f0-c79b47b22271.jpg?v=1624279944"},{"product_id":"hanna-instruments-98107-phep-ph-tester","title":"Hanna Instruments-98107 pHep pH Tester","description":"\u003cp\u003eThe Hanna Instruments-98107 pHep® revolutionised the pH industry by providing non-technical personnel with a simple, inexpensive solution to accurate pH measurement.\u003c\/p\u003e\n\u003cp\u003eThis pocket sized pH tester is used by millions of people around the world to monitor pH in laboratories and industrial applications as well as in agriculture, fish farming, food manufacturing and quality control, swimming pools and the printing industry.\u003c\/p\u003e\n\u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"section-row section 1\" id=\"description\"\u003e\n\u003cdiv class=\"section-text col-xs-12 rem-p-l rem-p-r\"\u003e\n\u003ch3\u003eHanna Instruments-98107 pHep pH Testers\u003c\/h3\u003e\n\u003cp\u003eWith a renewable cloth junction, the pHep® has an extended life over typical pH testers.

The ergonomic design allows this tester to fit comfortably in your hand. The large easy to read LCD display shows both EC or TDS and temperature along with calibration, stability and low battery indicators. All operations are simplified to two buttons. One is for turning the meter on\/off and the other for automatic one point calibration.\u003c\/p\u003e\n\u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"section-row section 1\" id=\"description\"\u003e\n\u003cdiv class=\"section-text col-xs-12 rem-p-l rem-p-r\"\u003e\n\u003cbr\u003e\n\u003cp\u003eThe GroLine Waterproof EC\/TDS Tester is made specifically for hydroponics, providing a simple, inexpensive solution to measure fertiliser concentration in a nutrient solution.\u003c\/p\u003e\n\u003cbr\u003e\n\u003cp\u003eThe Hanna Instruments-98318 EC\/TDS tester has a graphite sensor that reduces the polarisation effect common with amperometric testers that use two stainless steel pins.\u003c\/p\u003e\n\u003cbr\u003e\n\u003cp\u003eAutomatic calibration is achieved easily. Simply submerge the sensor in calibration solution and the meter will automatically detect the calibration standard (5.00 mS\/cm in Quick Cal mode or 1.41 mS\/cm in standard calibration mode). Temperature is automatically compensated for with the integrated temperature sensor.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cbr\u003e\n\u003c\/div\u003e\nKey Features\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"section-row section four\"\u003e\n\u003cdiv class=\"section-text col-xs-12 col-sm-7 add-p-r rem-p-l\"\u003eWaterproof\u003cbr\u003e\n\u003cp\u003eFast Automatic Temperature Compensation with exposed temperature probe\u003c\/p\u003e\nGraphite sensors that reduce polarisation effects\u003cbr\u003e\n\u003cp\u003e0.5 (500 ppm) and 0.7 (700 ppm) selectable EC to TDS conversion factors\u003c\/p\u003e\nSingle point automatic calibration using Quick Cal standard or 1.41 mS\/cm in standard calibration mode\u003cbr\u003e250 hour battery life\u003c\/div\u003e\n\u003cdiv class=\"section-text col-xs-12 col-sm-7 add-p-r rem-p-l\"\u003eEasy two button operation\u003c\/div\u003e\n\u003cbr\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":40354428289175,"sku":"HI-98318","price":76.76,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/5511\/6439\/files\/hi-98318-groline-waterproof-ec-tds-ppm-tester.jpg?v=1733756764"}],"url":"https:\/\/testallwater.co.uk\/collections\/garden-pocket-testers.oembed","provider":"Test All Water","version":"1.0","type":"link"}
