Process Sensor
pH sensor for pure water

Technical feature:

·

Adoption of the most advanced large Teflon diaphragm ,which make the sensor with stable liquid junction.

·

Adoption of sensitive glass membrane with low impedance effectively eliminate various interferences so as to make the

 

sensor response sensitively.

·

The reference system is filled with the high polymer,convenient to use, it is unnecessary to refilling KCL solution and it

 

can avoid the pollution on the tested liquid by KCL additive liquid.

·

The sensor is suitable for the pure water with the conductivity 1μs/cm. 

·

The pH range:0~14pH, temperature range: 0~80, pressure resistance of 0.6Mpa and zero point E07pH.

·
