Product Details
The Triplett GSM250 desktop indoor air quality CO2 meter is designed to monitor air quality in various settings such as office buildings, schools, exhibition halls, shopping malls, meeting rooms, fitness centers, and restaurants. It features simultaneous display of CO2, temperature, and relative humidity, and can be used as a desktop unit or mounted on a wall. The device includes a display with a light bar for readability from long distances, where a 3-color light bar (green/yellow/red) indicates CO2 concentration levels. This meter supports touch panel programming and offers a user-adjustable CO2 level alarm with the option to disable it. Utilizing NDIR (non-dispersive infrared) waveguide technology, it provides automatic baseline calibration (which can also be disabled) for long-term drift compensation or a 400ppm manual calibration option. The meter is powered via a USB source—either from a PC, power bank, or a 5VDC wall adapter (not included). The kit includes a 10ft (3m) USB-C cable for power source connection and a wall mount. It is backed by a 1-year warranty.
