General

Samon TR-EC-NH3 is a detector designed to measure the concentration of ammonia (NH3) in engine rooms, cold rooms, and other areas where ammonia is stored or utilised. The sensors are of electrochemical type with good selectivity and high accuracy even at low concentrations.  

The detectors provide a linear output signal (4..20mA) proportional to the concentration of ammonia.   Different measuring ranges are available depending on requirements and application. The electrochemical sensor has good selectivity and is not affected by hydrogen (H2) which is a common source of interference for ammonia detectors.
