GP-105 pH MEASURING HEAD FOR pH METERS OF 100 SERIES

GP-105 head may be used with all meters with pH measuring function from the 100 series. Those are: CP-101, CP-102, CP-103, CP-105, CPC-105 and CX-105. The GP-105 head is used for pH and temperature measurements of samples without or with only small deposits content. The head can't be used for viscous samples or those with deposits as they may clog the diaphragm.
For measurements with deposits, sewage, pastes etc. a GPX-105S head is necessary.
The GP-105 head may be used for measurements of:

drinking water,
tap water,
samples of water from rivers and lakes,
swimming pool water,
rain water etc.

In the plastic housing there are separate glass measuring and reference electrodes and temperature sensor.
Replacing the head is trouble-free, it is necessary to fit special shape of the head to the meter's body and tightly screw the nut.
The electrodes should be kept active by keeping a sponge, placed in the protective cap, wet.
For this purpose distilled water should be used.
