Carbon Dioxide (CO2)
Monitoring indoor air quality parameters can help minimize the risk of infection with viruses or bacteria, and increase overall well-being and concentration. With the advent of Covid-19, measuring and monitoring CO2 is more important than ever. Proper ventilation in crowded rooms can significantly reduce the risk of infection, including the coronavirus. Carbon dioxide (CO2) is a colorless and odorless gas that can be deadly in high concentrations. High levels of CO2 indoors can also be a strong indicator of inadequate ventilation, and continuous monitoring is essential for maintaining proper ventilation and indoor air quality in schools, offices, restaurants, warehouses and at home.
Datalogging Indoor Air Quality Meter
Poor air quality may cause tiredness, inability to concentrate, and even illness (i.e., Sick Building Syndrome). This instrument is ideal for measuring indoor air quality in crowded public spaces with potentially high levels of CO2 (carbon dioxide) such as offices, factories, classrooms, hospitals and hotels. The same measurement parameters can also be used to test air from HVAC equipment. Recalls the maximum and minimum CO2 readings and has a user selectable audible maximum alarm. Automatic Baseline Calibration (ABC) and maintenance free NDIR (non-dispersive infrared) CO2 sensor ensure long-term accuracy, stability and reliability. Calibrates to air and has a hold function. Records up to 32,000 data points of temperature, RH and CO2 that can be downloaded using a USB cable and software (included).
Comes complete with tripod screw, soft carrying case, 6 AAA batteries, AC Adapter (800059), USB computer cable and downloadable software. Please click the software download link above.

Indoor Air Quality Wall Monitor
Visible across a large room. Continually monitors the primary IAQ (Indoor Air Quality) parameters including: Air Temperature, Relative Humidity and CO2
Poor air quality may cause tiredness, inability to concentrate, and even illness (i.e., Sick Building Syndrome). This instrument is ideal for monitoring indoor air quality in crowded public spaces with potentially high levels of CO2 (carbon dioxide) such as offices, factories, classrooms, hospitals and hotels. Displays readings on a bright green LED display with 2½” high CO2 digits.
Also indicates general CO2 levels with green (good), yellow (fair), and red (poor) LED lights. User may set a maximum CO2 audible alarm and adjust temperature and RH readings to match any standard. Automatic Baseline Calibration (ABC) and maintenance free NDIR (non-dispersive infrared) CO2 sensor ensure long-term accuracy, stability and reliability. Can be wall mounted, or will stand on a shelf or desktop. Includes AC adaptor.
