Hello I am looking for suggestion and information regarding gas sensor microchip and integrated wireless transceiver. The details of gas sensors are as follows: 1. Gas monitoring is routinely done to check for the presence of hydro carbon gases (LNG, LPG) in the confined spaces of vessels. These checks are basically done to determine the % LEL. 2. Besides monitoring spaces for flammable gases, gas checks are also carried out, at times, to determine toxicity (ppm) levels. Some of the gases, commonly checked for, are as follows :- ( i) Hydrogen Sulphide ( ii) Ammonia (iii) Vinyl Chloride Monomer (iv) Benzene ( v) Carbon Monoxide Gas checks for toxicity are carried out depending on the cargo manifests. Gas Detector tubes are normally used for such monitoring. Who has this kind of devices or technology?
