Desktop Indoor Air Quality CO2 Monitor

The CO220 Desktop Indoor Air Quality CO2 Monitor provides a comprehensive and accurate assessment of your indoor environment by measuring carbon dioxide (CO2), air temperature, and humidity levels. This essential tool is designed for any setting where air quality is a concern, helping to ensure a safe, comfortable, and productive atmosphere.

At its core is a highly accurate, maintenance-free NDIR (Non-Dispersive InfraRed) CO2 sensor. This technology reliably detects CO2 concentrations from 0 to 9999 ppm, with readings clearly displayed on the screen. Six intuitive facial icons provide an instant, easy-to-understand visual indicator of the current indoor air quality level, from good to poor.

Beyond basic measurements, the monitor performs sophisticated calculations for dew point and wet bulb values. It also provides vital ventilation metrics in both lps% (litres per second per person) and cfm/p (cubic feet per minute per person), making it an invaluable tool for HVAC professionals and facilities managers. For safety compliance, it calculates statistical weighted averages for the TWA (8-hour Time Weighted Average) and STEL (15-minute Short Term Exposure Limit).

Practical features enhance its usability. An audible warning alarm alerts you when CO2 levels exceed your predefined high or low set points. The device includes a min./max. value recall function, allows you to manually store and recall up to 99 readings, and performs an automatic baseline calibration. It also displays the current date and time.

Supplied complete with an AC power adaptor fitted with a UK mains plug (type G), it is ready for use straight out of the box. With its compact desktop design, robust operating range (-10°C to 60°C, 0.1% to 99.9% RH), and suite of professional features, this monitor is a reliable choice for maintaining optimal indoor air quality.
