connected externally, for working conditions where
solid electrolyte not applicable
Biological process, viscous
mediums, organic solvent, ethyl
alcohol
Fiber diaphragm Normal pressure, solid electrolyte filling, plastic
outer pipe
Laboratory electrode

 

Attention:

PH electrodes are consumables. Storing PH electrode will also consume its service life, so we don’t recommend buying too many electrodes at once. We have a large number of various types of semi-finished product of PH electrode. It is convenient to provide the fresh PH electrodes for the user.
