Hanna Instruments HI-12973 Titanium Bodied pH and ORP Electrode with Quick Connect Din Connector
pH/ORP/temperature probe with titanium body and DIN connector with 1m (3.3’) cable. Recommended for use in wastewater, municipal water, water treatment and swimming pools.
The HI-12973 pH/ORP probe has a built in temperature sensor for simultaneous temperature compensated pH and temperature readings, and contains a preamplifier to provide stable measurements in electrically noisy environments. The probe contain a pH sensor with cylindrically shaped bulb.
The probe also contains a single junction gel filled Ag/AgCl reference electrode with a cloth junction. Should the junction become dirty, simply pull out the cloth and trim off that portion. The ORP sensor is platinum and utilizes the same reference electrode as the pH electrode. Voltages displayed from this sensor are referenced to the Ag/AgCl reference with 3.5M KCl activity.
