The A37 CO2 Meter is a compact device for monitoring indoor air quality. Its easy-to-read LCD screen displays CO2 levels, temperature, humidity, and time, so all key data is immediately available. The NDIR sensor, combined with automatic calibration, ensures stable and reliable measurements, which translates to better control of environmental conditions. If the safe CO2 level is exceeded, an audible and visual alarm is triggered, allowing you to react quickly. Additional features, such as a backlight, auto-off, and low-battery indicator, enhance the convenience of daily use.
