CO2 Gas Detector PCE-7755

CO2 gas detector PCE-7755 

portable CO2, temperature, and relative humidity detector

Affordable portable gas detector with which you can check air quality. The gas detector has a dual display with 3 simultaneous parameters for CO2, temperature, and humidity, and with backlighting for low-light conditions. The gas detector features NDIR (non-dispersive infrared) wave technology sensor. Manual calibration is recommended, and it is easy to calibrate outdoors around 380 - 420 ppm. The gas detector has a Hold function that fixes the current measurement readings on the display for 8 hours (time-weighted average function) or for 15 minutes (short-term exposure limit). It also includes max., min., and average functions. It has several warning signals for CO2 levels, such as an audible alarm of ~ 80 db.
