LEAR Siegler can provide a dedicated gas membrane galvanic wet scrubber sensor which can fit directly into a wet scrubber in many cases doing away with expensive, labour intensive extraction systems and slow acting unreliable hard or gel type (common round) electrochemical (EC) sensors.
Applications include wet scrubbers, waste water treatment plants, semiconductor manufactures, chemical dosing in scrubbers, cold storage facilities, and more.
Hard or gel type EC sensors typically require an externally applied current from a transmitter to operate which have high noise levels that in turn limit their ability to detect low level concentrations.
Changes in temperature and humidity generate additional background current adding to noise and distorting readings. It is well known that the use of amplifiers (or bias potential) and filters on hard or gel type EC cells does not significantly increase sensitivity.
