The AST-I series of analog transmitters are high quality, industrial, dual beam, referenced transmitters with miniature infrared sensors, analog output and water / dust tight, corrosion resistant, non-metallic enclosures.
The AST-ICD detects carbon dioxide (CO2) with a choice of one of three different ranges.
The AST-IHC detects hydrocarbons, methane (CH4) and jet fuel vapours.
Care should be taken to not spray the sensor head in wet environments. The sensor vent opening has a microporous PTFE filter attached which provides splash protection only, it is not designed to provide protection from the application of pressurized water.
