The Detcon Model DM-502IS-NH3 Detector is designed to continuously detect and monitor NH3 in air in the 0 to 100 ppm range.
The sensor assembly consists of an electrochemical fuel cell mounted in a stainless steel and ABS plastic casing incorporating a splash guard with integrated heat port, a signal conditioning control transmitter circuit, a base board and a explosion-proof junction box.
The intrinsically safe sensor housing design allows direct contact of the target gas with the electrochemical sensor, maximizing response time, detectability and repeatability.
And because the intrinsically safe case design does not use stainless steel flame arresters, it eliminates inaccurate readings due to target gas absorption.
