pH/pH-mV/ORP and Temperature Meters HI991003
| Previous | 2 / 15 | Next |
The HI991001, HI991002 and HI991003 are ideal 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.
