Hanna HI 9812-51 External Probe pH, EC, TDS, Temperature Meter

Hanna HI 9812-51 External Probe pH, EC, TDS, Temperature Meter

• HI 9812-51 is a complete, versatile, and rainproof portable pH and conductivity measuring device specially produced for aquariums, fish farming, and marine water applications.

• Hanna HI9812-51 measuring device is a precise instrument capable of measuring pH, conductivity (EC and TDS), and temperature.

• The device can also be used for measuring greenhouse irrigation fluids, in agriculture, and various liquid controls.

• pH measurement is performed with the "pH unit", EC measurement with the "µS/cm unit", TDS measurement with the "ppm unit", and temperature measurement with the "°C unit".

• Thanks to its large LCD screen, it is quite comfortable to read measurements and use the device.

• For the highest accuracy, the device must be calibrated frequently. Calibration should be performed every time the electrode is changed, at least once a month, immediately after measuring with harsh chemical liquids, and before every measurement requiring extreme sensitivity.

• Calibration for pH and conductivity is done separately with the rotating mechanisms located at the bottom of the device.

• With the ATC (Automatic Temperature Compensation) feature present in the device, temperature compensation is automatically performed.

• The HI 1285-5 probe included in the package should be covered with the protective cap when not in use to prevent damage, and the potassium chloride protective liquid inside the cap should always be present.

• A manufacturer test certificate is included in the device box.
