pH/pH-mV/ORP and Temperature Meters HI991002
Quantity
The HI991001, HI991002 and HI991003 are ideal meters for plating baths, waste water, swimming pool and spa water quality, as well as environmental applications. HI 991003 is a portable pH/pH-mV/ORP/temperature meter with our unique Sensor Check™ feature that allows the user to determine the electrode status at any time. HI 991002 measures pH/ORP/temperature while the HI 991001 measures pH/temperature. The HI1296D pH/temperature and HI1297D pH/ORP/temperature probes feature an easy-to-clean recessed tip that prevents solids in solutions from collecting on the sensor. The AISI 316 stainless steel and titanium body of these probes function as a potential matching pin for increased stability of readings and extended sensor life.
