Gassdetektor NH3 (Ammoniakk)
Monicon T100 (4-20mA) gassdetektor NH3.
Produsentens beskrivelse av gassdetektor NH3 (Ammonia):
The Monicon T100 is a 4-20mA 2-wire transmitter can measure a wide range of gases and is housed in a rugged, compact metallic enclosure. It incorporates advanced SMD electronics and a 3 electrode electrochemical sensor based on micro fuel cell technology, designed to be maintenance free and inherently stable.
The sensor uses the highly successful capillary diffusion barrier technology, resulting in a low temperature coefficient and a direct response to concentration, relatively unaffected by pressure. The use of electrodes based on fuel cell technology gives a high reserve of activity which results in long term stability.
Gas diffusing to the sensor electrode reacts at the surface of the electrode either by oxidation (e.g. CO, H2S, SO2, NO, H2, HCN, HCl, C2H4O, NH3) or by reduction (NO2, O3 and Cl2). Reactions are catalysed by specially developed electrode materials and are designed to be specific to the gas being sensed.
