CO2 Sensors

Available on backorder

Features :

CO2 Sensor

Nondispersive infrared (NDIR) technology measures CO2 levels in ppm. May be used as a handheld portable (internal, rechargeable battery) or wall-mounted for continous recording and data logging with a WatchDog Data Logger (one CO2 meter per logger).

Includes 6-volt DC transformer. Range: 0-4,000 ppm. Accuracy: +/- 5% of reading or 50 ppm, whichever is greater.
