HI98120  ORP/Temperature Tester

The HI98120 is a waterproof ORP and temperature meter, while HI98121 measures pH, ORP and temperature. The housing of these testers has been completely sealed against humidity and are designed to float. Electrode replacement with the stainless steel round connector means there are no pins to bend or break during replacement. When the cloth junction becomes clogged and response time is sluggish, simply pull out 3 mm (1/8”) to clear the clogging which will improve response time and stability.The exposed stainless steel temperature sensor on these models facilitates faster and more accurate temperature measurement.
