CO2 gas detector (carbon dioxide)


CO2 (carbon dioxide) is a colorless and odorless gas and its major related hazard is about its asphyxiating properties. As it is heavier than air and is not detectable through smell, it replaces oxygen in the air in case of leak in fermenting process or in poorly ventilated spaces such as crawl spaces, manholes, pits, sewers, tanks…


In order to prevent any risk related to this gas, it is highly recommended to implement a fixed CO2 gas detection system – when it’s not required – in order to continuously monitor carbon dioxide concentration in ambient air and to alert (audible and/or visual signal) or take actions (mechanical ventilation) if necessary. In addition to this fixed gas detection system, a portable CO2 gas detector used as a PPE (personal protective equipment) can be relevant.


CTX300 IRCO2 CO2 detector assets


  • Reduced maintenance: the CTX 300 IRCO2 measuring sensor is the only consumable item and is interchangeable and factory pre-calibrated with attached calibration certificate.
  • Ease of use: no particular sensor data memorization or validation shall be performed when replacing a sensor. Just replace sensors without shutting down power supply!
  • Powerful sensors: infrared sensors to detect CO2 from 5,000 ppm to 100%/vol.
  • Foolproof ruggedness: Case made of polycarbonate and stainless steel fibers and staliness steel screws, resistant to corrosive agents (H2S, HCl, sprays…) and high mechanical resistance
  • Adapted options: Interchangeable removable filters without case opening (dust and water resistant), anti-spray unit, gas collector, remote calibration cup...
