CO2 Monitors

High-quality CO2 monitors, designed to provide accurate and reliable carbon dioxide measurements for various indoor environments. Our selection includes cutting-edge non-dispersive infrared (NDIR) CO2 monitors, meters, and data loggers.

Whether you need a portable handheld device for spot checks or a mains-powered industrial CO2 data logger for continuous monitoring, we have the perfect solution for your needs. Our CO2 monitors offer features such as real-time displays, data logging capabilities, and mobile device compatibility, making it easy to track and analyse carbon dioxide levels in offices, schools, laboratories, and industrial settings. As the exclusive UK and Ireland distributor for Onset HOBO carbon dioxide data loggers, we pride ourselves on offering superior accuracy and build quality in our CO2 monitoring solutions.

Scientific and medical research correlates poor indoor-air quality (IAQ) and elevated carbon dioxide (CO2) levels to occupant discomfort and productivity loss in offices, schools, healthcare facilities, and dwellings [1-5].

CO2 is a trace pollutant that impairs cognitive and respiratory function.

Sustained concentrations exceeding 600-700 parts per million (ppm) over outside levels are associated with inadequate ventilation and, thus, serve as a convenient proxy for overall indoor-air health [6].

The U.S. Environmental Protection Agency (EPA) identified IAQ as one of the top five most urgent environmental risks to public health [7]. Facility managers and building engineers are often responsible for ensuring optimal ventilation in work and living spaces, yet many are unfamiliar with the scientific rationale or methods to achieve such control. Wireless data loggers that measure CO2, together with temperature and humidity, provide critical real-time awareness—essential to enforcing high environmental standards for occupants.

With long-term CO2 monitoring, building operators gain insights to support better decisions regarding ventilation control and HVAC upgrades—projects that can lead to significant energy savings and improved overall indoor-air quality.

Comprehensive, location-specific CO2 data in building environments also helps to focus HVAC improvements on the most effective and cost-efficient solutions.

CO2 data loggers provide a cost-effective method to assess indoor air quality, helping to eliminate sick-building syndrome and harmful pollutants typical of tight and poorly ventilated structures.

Fortunately, battery-powered CO2 data loggers easily measure indoor concentrations. These compact hand-held devices—roughly the same size and shape as a wall-mounted home thermostat—may reside anywhere throughout a building where CO2 data is needed. Measurements typically range from 0–5,000 ppm. Today’s newer options enable users to access data from mobile devices and quickly download data directly to a laptop, or from the cloud.

• Tight-building standards increase risk of sick-building syndrome and poor occupant health
  • Offices, schools, healthcare facilities, gyms, and dwellings frequently exceed healthy CO2 levels
  • Indoor CO2 concentration over 1,000 ppm correlates to cognitive impairment and dysfunction
  • Global CO2 exposure limits vary by country, some more stringent than US standards
  • Bluetooth, long battery life, LCD display with alarms, and USB options facilitate data collection
  • Automated CO2 logger calibration and proper placement improve measurement accuracy.
