Ammonia Gas Detector Singapore | NH3 Detector Ammonia

Ammonia (NH3 ) is colourless gas and has a pungent suffocating smell. It is corrosive and overexposure can cause immediate burning of the eyes, nose, throat and respiratory tract. It can lead to blindness, damage in the lung or even death. Inhalation of lower concentrations can result in coughing and irritation of nose and throat. According to OSHA, 25 ppm is the permissible level for Ammonia ...

A possibility of application of an electrochemical sensor based on a liquid electrolyte of NH3/MR 100 type [4] as a comparative gassensing element was tested in experiments with ammoniaair mixtures. The try was unsuccessful due to the dry gas thinner (air) and absolute insensibility of the electrochemical sensor to ammonia. This result has shown that this measuring mode is in complete ...

20180105· Different concentrations of NH 3 were obtained by diluting standard NH 3 (NH 3 in N 2, Qingdao Ai Ruo Gas Co. Ltd.) with dry compressed N 2 using computerdriven digital mass flow controllers. The sensor response is defined as S = R a /R g, where R a is the resistance of the material exposed to background atmosphere and R g is the resistance of the material to a certain target gas ...
