Built for continuous room monitoring, this unit reads CO2, temperature, and humidity on a 7-inch color touchscreen and uses a low-drift NDIR sensor to hold its accuracy over time. It can sit on a desktop or be wall-mounted using the included bracket, with programmable alarm thresholds and logged data exportable to a computer for review. The package includes a USB cable, power adapter, mounting bracket, and a NIST-traceable calibration certificate.
