PRELIMINARY EXAMINATION

HI 981402 and HI 981403 are pH meters 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 and HI 2114P/2 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.

pH ELECTRODE CONNECTION & MAINTENANCE

In order to protect the instrument against

vapors and humidity, the BNC connector is

shielded behind a waterproof sheath.
• Slide the protective sheath down. Connect the pH

electrode to the BNC connector and then slide the

protective sheath back up all the way up to the casing.

Since the protective sheath is rubberized to ensure

maximum waterproof protection, make sure the connec-

tor is completely covered.
