Carbon Monoxide (CO) Detector, Basic version, CMA, CMK and CMR-series

carbon monoxide detector CMA

carbon monoxide detector with duct mounting set CMK

carbon monoxide detector with stainless steel enclosure CMK

The carbon monoxide detector with output 4-20 mA or 2- 10 Vdc is used for the continuous monitoring of the ambient air to detect the presence of carbon monoxide (CO) gas concentrations within the ambient conditions defined in the specifications.

Main application ranges for the carbon monoxide detectors are underground car parks, tunnels, engine test stations, shelters, loading areas etc.

The Carbon Monoxide (CO) sensor it-self is a posioning stable electrochemical sensor and have 5 years life time expectancy in normal operation enviroment.

The 3 different series in Basic version of
Carbon Monoxide (CO) Detector

CMA-series, Carbon Monoxide (CO) Detector
with IP65 plastic enclosure for wall mounting.

CMK-series, Carbon Monoxide (CO) Detector
with IP65 plastic enclosure supplied with duct mounting set for duct mounting.

CMR-series, Carbon Monoxide (CO) Detector
with stainless steel enclosure for wall mounting designed with a practical snap closing without screwing. To avoid unauthorized opening, the CMR enclosure in stainless steel can only be opened by opening tool TL1 SSE

Features for the Basic version of
Carbon Monoxide (CO) Detector
CMA, CMK and CMR-series:

  • Supply voltage 18-28 Vdc
  • Outputs 4-20 mA or 2-10 Vdc
  • Measuring ranges
    0-50 ppm,0-100 ppm, 0-150 ppm, 0-200 ppm, 0-300 ppm,
