1R39 probe is specially designed for conductivity or resistitvity measurement in drain assembly. Collinear electrodes in 316L SS have almost an unlimited life in normal operation mode.

A PVC connection, 1/2‘’ male (or 1/4‘’) threaded connection, allows an easy fixation. Standard length of the probe is 50mm. Standard length of the coaxial cable is 3m (length can be adjusted on request).

Cleanliness of the electrodes is very important in order to obtain an accurate measurement. Both electrodes have to be smooth and shiny. A check-up is necessary regularly (every month).

Least dirtiness can short-circuited the electrodes and give a wrong measurement.

The electrodes can be cleaned passing a rag between them.
(Nota: the probe in the air gives an infinite measurement and «zero» in short-circuit).
