2.2.3 EHAN sensor: Redox and temperature.
The PONSEL sensor incorporates a reference electrode, used for ORP measurements, such as Ag /
AgCl in saturated KCl electrolyte plasticized "PLASTOGEL" ®.
The electrolyte "PLASTOGEL" ® communicates directly with the external environment without
interposition of capillary or porous. So there is no risk of clogging or defusing the reference.
The measuring electrode is in platinum (3,5mm2) presented in sealed ring on a glass rod and is for in-
situ measurements continuously
Temperature: measures via CTN.
