HI991001, HI991002 and HI991003
are ideal for plating baths, wastewater,
swimming pool and spa water quality
and environmental applications.
HI991003 is a portable pH/pH-mV/ORP
and temperature meter with our unique
Sensor Check™ feature that allows the
user to determine the electrode status
at any time. HI991002 measures pH/ORP
and temperature while the HI991001
measures pH and 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
titanium body of these probes function as a
potential matching pin for increased stability
of readings and extended sensor life.
