FAQ About Ammonia Gas Detection Systems

Feb 27, 2018· Ammonia is lighter than air and collects at the ceiling (or the highest point of the room). Therefore the gas detector/sensor should be mounted on or at the ceiling. If you were to mount the detector at breathing height ( - m / 4 - 6 ft from the floor), the concentration of ammonia would start at the ceiling and move down towards the ...

Why do I See Negative Readings on my Gas Monitor?

Sep 18, 2019· If an H2S sensor has an offset of -10 PPM due to sensor drift or a false zero operation and negative readings have been masked by the manufacturer, exposure in a true concentration of +10 PPM will still produce a zero reading and a concentration of +20 PPM would only be displayed as 10. This situation would be easier to recognize if the ...
