CO2 industrial gas detector

 gas safety solution for industries


PLEASE NOTE: For proper installation of the ESCM-900 or ESCM-902 industrial gas detectors, the device must be hard-wired, and a ESCM-900-CBL OR ESCM-900-CON MUST be purchased with this device.


The ESCM-900: COIndustrial Fixed Gas Detector is a gas safety solution for industries that need to measure up to 5% carbon dioxide levels to mitigate potential hazards. This device also includes an IP64 industrial enclosure specifically for harsh environments or where wash-down is required.


  • Fast and Precise CO2 measurements - monitors 0-5%
  • Gain instant audible or visual alarms for potential leaks
  • Users configurable 3-relays dependent upon application
  • Meets all NFPA, IFC, and NBIC CO2 Safety Code Requirements
  • 4-20mA output to communicate with (BMS) Building Management Systems
