For monitoring:

Carbon dioxide, Hydrocarbons, Methane and jet fuel vapours

 

Key Features

  • Single sensor
  • Low power consumption
  • Dual temperature compensated pyroelectric infrared detectors
  • Fast response with accurate low-level gas detection
  • Long sensor life
  • Water / dust tight / corrosion resistant polycarbonate enclosure
  • Linear analog (4 - 20 mA) output

 

Description

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.
