Specification of HI76309

The four ring construction is designed to ensure the probe is immune to polarisation and fouling for longer periods of time. Combined with a one meter cable, this probe makes the meter particularly popular for use in a variety of applications both in the laboratory and out in the field.

Supplied with

HI-76309 probe with internal temperature sensor on 1m cable
Batteries
Instructions
Rugged carrying case
