HI 991003, HI 991002 and HI 991003
pH/pH-MV/ORP PORTABLE METERS
The HI 991003, HI 991002 and HI 991001 are well suited for plating baths, wastewater,
swimming pool and spa water quality and 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 HI 1296D and HI 1297D pH probes feature a recessed flat tip that is easy to
clean and prevents solids in solutions from collecting on the sensor. The titanium
body of these probes function as a potential matching pin for increased stability of
readings and extended sensor life.
These instruments easily fit in the palm of your hand and the bottom probe connection
ensures the electrode cable doesn’t get in your way. The large, multi-level LCD displays
the primary reading, temperature and calibration instructions simultaneously.
