The HI 9835 combines the four important parameters needed to measure conductivity in one high precision multiparameter instrument
Designed to allow simultaneous sampling of electro conductivity (EC), total dissolved solids (TDS) sodium chloride (NaCl) and temperature, this is a great portable meter for measuring conductivity in testing or pressured environments.
Key features
The HI 76309 conductivity and temperature probe features a PVC body with a stainless steel four ring design to deliver high accuracy over a broader conductivity range.
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
