The basic version is the in-line model which allows for direct installation of probe and chemical injection fittings into existing piping. A panel mounted version with a bypass flow cell is also available. The bypass flow cell allows for calibration and maintenance of the probe without having to shut down the recirculation pump.\u003c\/p\u003e \u003cp\u003eFor compliance monitoring, BL122 has a built-in datalogger. Measurement readings are logged every 10 seconds with a new log starting for each new day or when the instrument is calibrated.\u003c\/p\u003e \u003cp\u003eLogged data include pH, ORP, and temperature values, last calibration data, setup configuration, and any event data.\u003c\/p\u003e \u003cp\u003eThe chlorine level is measured based on the ORP or REDOX principle. An increase of the ORP value correlates with an increase of the free chlorine level. pH and disinfectant tests are made together for more efficient disinfection and control. The efficacy of sanitisers is dependent on a controlled pH value. The ORP value is the most consistent indicator of the sanitising effectiveness of the pool\/hot tub or water treatment. Typically 650-750 mV at 7.2 pH indicates proper water treatment (all harmful bacteria are killed in less than 1s). pH and disinfectant tests are made using the HI-1036-1802 combined electrode installed in-line or in flow cell. To prevent the ground loop effects from causing erratic readings and damage to the system the electrode has a matching pin considered the ‘earth ground’ connection.\u003c\/p\u003e \u003cp\u003eIt was specially designed to detect the broken electrode based on a shifted isopotential value. The HI-1036-1802 uses an Ag\/AgCl reference with 3.5 M KCl. The ORP values are referenced to it.\u003c\/p\u003e \u003ch3\u003eThree Display Modes\u003c\/h3\u003e \u003cp\u003eThe versatile display of the BL122 allows for three display modes. The LCD can display all three parameters at one time, a 3-second cycle of single parameters, or a real-time plot screen with options for parameter selection, zooming, and log recall.\u003c\/p\u003e \u003ch3\u003eKeep Track Anywhere with Hanna Cloud Connectivity\u003c\/h3\u003e \u003cp\u003eHanna Cloud is a web based application that connects you to measurement devices such as the BL122.

With chlorine disinfection there is an inverse relationship between pH and ORP. As the pH level increases, the ORP level decreases. These meters utilize a dosing consent feature that will not dose chlorine until the pH value is first corrected since it is possible to have a low ORP value even though there is sufficient chlorine. The dosing consent feature prevents waste of chemicals and avoids having a higher chlorine concentration level than desired.\u003c\/p\u003e \u003cp\u003e\u003cb\u003eAcid and Chlorine Tank Level Inputs\u003c\/b\u003e\u003c\/p\u003e \u003cp\u003eThe BL122 allows for a connection to an optional level controller. This input is used to disable the dosing pumps when there is no chemical left in the reservoir tank.\u003c\/p\u003e \u003cp\u003e\u003cb\u003ePeristaltic Chemical Feed Pumps\u003c\/b\u003e\u003c\/p\u003e \u003cp\u003eBL122 are equipped with two peristaltic dosing pumps with replaceable chemical resistant tubing that are proportionally controlled with adjustable flow rates. One of the pumps is used to dose acid or base while the other is used to dose chlorine. The effectiveness of the available chlorine, as determined by ORP, is inversely related to the water’s pH value.\u003c\/p\u003e \u003cp\u003e\u003cb\u003eMulti-coloured LED Indicators\u003c\/b\u003e\u003c\/p\u003e \u003cp\u003eBL122 offer multiple LED indicators for status, servicing, and pump operation. The STATUS LED changes colour based on operational state; a green LED means the water is within the desired parameter ranges, a yellow LED means that the controller needs attention, and a red LED identifies a problem in the system such as high and low pH, ORP and\/or temperature readings. The SERVICE LED indicates attention is required by a service technician.\u003c\/p\u003e \u003cp\u003e\u003cb\u003eAutomatic Proportional Pump Control\u003c\/b\u003e\u003c\/p\u003e \u003cp\u003eBL122 features proportionally controlled dosing pumps. Based on the sensitivity of the process to chemical addition, these controllers allow the user to adjust a proportional band.\u003c\/p\u003e \u003cp\u003eThis setting determines the amount of time that the pumps are dosing as a percentage of the deviation from the set point. For example, a large body of water will use a small proportional band; having a small band (e.g., 0.1 pH) will ensure the pumps are dosing more often when the reading is close to the set point. For smaller bodies of water such as hot tubs or spas, it is more useful to set a larger proportional band (e.g.,1.0 pH); when the reading is close to the set point, the amount of time that the dosing pump is on is minimal to avoid large swings of pH or ORP.\u003c\/p\u003e \u003cp\u003eThis valuable feature allows for very fine control in maintaining the desired set point.\u003c\/p\u003e \u003cp\u003e\u003cb\u003eAdjustable Flow Rate\u003c\/b\u003e\u003c\/p\u003e \u003cp\u003eThe dosing pump flow rate is adjustable from 0.5 to 3.5L\/h. Larger bodies of water require more chemical to be dosed than small bodies since it takes more chemical to see a change in the reading. The adjustable flow rate, like the proportional band, allows for better control in maintaining a desired set point.\u003c\/p\u003e \u003cp\u003e\u003cb\u003eORP (Chlorine) Dosing Consent\u003c\/b\u003e\u003c\/p\u003e \u003cp\u003eBoth pH and ORP meters are commonly used with swimming pools.

When an alarm is activated, all dosing will stop. The alarm system also offers overdosing protection, in that if the value is not corrected within a specified time interval then the meter will go into alarm status.\u003c\/p\u003e \u003cp\u003e\u003cb\u003eAutomatic Logging\u003c\/b\u003e\u003c\/p\u003e \u003cp\u003eThe readings for each parameter are automatically logged every 10 seconds.

This probe also incorporates a potential matching pin. The matching pin is considered the “earth ground” connection and is used to prevent ground loop effects from causing erratic readings and damage to the system.\u003c\/p\u003e \u003cp\u003eThe pH glass has been chosen to produce stable quick equilibration even in low conductivity waters. Additionally, the pH sensor is designed to produce a zero mV value near pH 4 (not pH 7 like typical pH sensors) that will stop the process control when the sensor is broken. A broken pH electrode that produces a mV value near pH 4 would produce an alarm state and disable any pump activated.\u003c\/p\u003e \u003cp\u003eThe ORP sensing surface is a large smooth surfaced platinum band that encircles the circumference of the temperature probe. It is referenced to Ag\/AgCl reference electrode (3.5M KCl).\u003c\/p\u003e \u003cp\u003eThe ORP and pH sensors and reference electrode use a differential measurement technique which is known to stay in service and provide accurate measurements under adverse conditions that may cause conventional pH probes to produce erroneous measurements.\u003c\/p\u003e \u003cp\u003eThe HI-1036-1802 probe with its differential amplifiers greatly reduces inaccuracies caused by ground loops which may exist between process and instrument grounds. With the differential technique, a ground loop current will flow through the low impedance path of the matching pin thus providing immunity to the measurement signals. Additionally the probe converts these measurements to a digital signal to eliminate noise and static due to high impedance signals carried by cable.\u003c\/p\u003e \u003cp\u003eThe HI-1036-1802 with the BL122 pool controller helps to promote the health and safety of pool and spa water.\u003c\/p\u003e \u003cp\u003eFor BL123 models, three 4-20 mA analog outputs are available for users that wish to connect to an external chart recorder or datalogger to monitor any of the three measured parameters.
