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.
