For continuous pH/ORP measurement, especially under the difficult conditions very often found in sewage treatment facilities, very high demands are made concerning the reliability and operating safety of the systems employed.
SensoLyt® SEA / SE*
This pressure and temperature resistant combination pH electrode incorporates a double pin-hole diaphragm and a gel polymer solid electrolyte, which is AgCl free and therefore resistant to sulfides.
•Highly contaminated sewage
•Emulsions and suspensions
•Media containing proteins and sulfides
pH 2 … 12
Operation conditions
(Overpressure/temperature)
10 bar / 20°C
1 bar / 60°C
0 … 60 °C
SensoLyt® SEA-HP
Analog SensoLyt® SEA version, with optimized armoring for use under high pressure / temperature conditions.
•Inline measurement in pipes
pH 4 … 12
Operation conditions
(Overpressure/temperature)
10 bar / 60°C
