HI 981402 is pH meter specially designed to meet the needs of simple continuous monitoring of pH. The housing has been completely sealed against vapors and humidity with IP54 rating. You can simply hang the meter right above the sample to be tested for continuous measurement.
The HI 1286 gel-filled pH electrodes are interchangeable and the BNC connector is protected behind a waterproof sheath. The unique design of the electrode provides longer life even in aggressive solutions. You can even select your own setpoint and be alerted of an abnormal situation with a flashing LED alarm.
Measurements are highly accurate and the meter can be calibrated at one or two points. You no longer need to worry about battery changes either: the unit runs without interruption on 12 VDC power supply.
