CO2 Gas Detector (with bracket)

MK9 CO₂ Safety system

The Mk9 CO₂ sensor is the latest generation of CO₂ Safety Systems and has replaced the LogiCO2 MkVII CO₂ Sensor System. A large display, functional design and revolutionary language functionalities are some of the new features of the MK9 CO₂ Safety System. The display alternates between actual CO₂ concentration (0.0%- 6,7%), TWA (ppm) and temperature (°C or°F), (if temperature alarm is activated for cold room applications).

This complete plug and play SET contains a Mk9 CO₂ Sensor with display, a Mk9 Central Unit to display the measured values, a Horn/strobe, cabling and signage. Up to twelve sensors can be connected to the Mk9 CO₂ Safety Detector SET, providing a sophisticated and powerful CO₂ Safety System while still being the most economical and easiest system on the market. All LogiCO2 sensors have automatically calibration as standard. The alarm levels can be changed to any level to comply with all local Safety Codes and legislation.
