How will Ammonia or Ammonium Hydroxide evaporate / condensate effect the reading of an electrochemical O2 sensor?
Ammonia or Ammonium Hydroxide evaporate / condensate will effect sensor performance. If it condenses on the surface of the sensing membrane, it will block the sensing area making the output erratic. Any condensate over the sensing area will do the same (including water). Most importantly, Ammonia or Ammonium Hydroxide evaporate / condensation will effect the sensor physically. It will have a corrosive effect, corroding the contact plate. Then the output will decrease or will be erratic. Also, it will react with the adhesive on the sensor label, and label will peel off the sensor.
