3900 and 3900VP pH/ORP general purpose sensors sensors

3900 and 3900VP pH/ORP general purpose sensors sensors
Manufacturer:
ЭКОХИМПРИБОР

3900 and 3900VP models are equipped with dual electrolyte tank, which serves for reference electrode protection against ammonia, chlorine, cyanide and sulphide ions pollution. Both models have membrane made of porous teflon located close to sensitive pH/ORP membrane. 3900 and 3900VP model sensors have in-built SMART option allowing to carry out automatic data exchange about calibration timing and intervals, data storage and pH diagnostics (inclination, displacement, reference impedance, glass impedance). Sensors are fixed in a leak-proof chemically resistant casing made of polyphenylene sulphide.
