PH Electrode structure:
● Glass rod type PH electrode (Connection : PG 13.5 or M20*1.5)
● PH Measuring range: depending on the Sensitive film
● Operation temperature: depending on the Sensitive film
● Operation pressure: depending on the Diaphragm
● Temperature compensation: NTC: 0 ~ 100 ℃, 2 wire; PT100: -20 ~ 130 ℃, 3 wire; PT1000: -20 ~ 130 ℃, 3 wire
● Electrode cable type: Separate cable or Fixed cable
● Cable length: customized
Sensitive film option:
|Sensitive film||Usage||Best measuring range||Temperature range|
|PR film||General industrial process||0 – 13 PH||0 ~ 80 ℃|
|LT film||General industrial process||0 – 13 PH||-20 ~ 80 ℃|
|HAT film||Strong alkali||3 – 14 PH||0 ~ 120 ℃|
|HS film||Strong acid||0 – 9 PH||0 ~ 100 ℃|
|LTS film||Fermentation disinfection process||2 – 12 PH||0 ~ 130 ℃|
|Polymer film||Fluids with F||0 – 13 PH||-10 ~ 60 ℃|
|Platinum needle||ORP electrode (reducing fluids)||-1999 ~ 1999 mV||-10 ~ 130 ℃|
|Golden needle||ORP electrode (oxidant)||-1999 ~ 1999 mV||-10 ~ 130 ℃|
|Remark: Golden needle can not be used for occasions containing fluorinion / chloridion / Cyanide ion / O3.|
|Teflon diaphragm||Pressure ≤ 0.6 MPa, can be disinfected,
anti-blocking, anti-stained, Solid electrolyte filling,
anti-poisoning, long electrolytic bridge
|Most industrial occasions|
|Annular gap||Pressure ≤ 0.6 MPa, without diaphragm, without
blocking, Solid electrolyte filling, anti-poisoning,
long electrolytic bridge
|Sewage, industrial waste water|
|Pressure ≤ 0.8 MPa (with counter pressure), liquid
KCL filling, counter pressure liquid adding container
connected externally, for working conditions where
solid electrolyte not applicable
|Biological process, viscous
mediums, organic solvent, ethyl
|Fiber diaphragm||Normal pressure, solid electrolyte filling, plastic
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.
