The rechargeable carbon dioxide detector adopts NDIR sensor to real time monitoring the CO2 concentration, and display the current temperature, humidity, date and time at the 3.8-inch large LCD screen.

Features:
3.8-inch LCD Screen: real time display the current CO2 concentration, air temperature(°C/°F switchable), humidity, air quality condition(good/normal/poor), battery indicator, calendar(year, month, date) and time.
Touch Key Control: touch key at the front panel to check the MAX/MIN value of carbon dioxide (CO2) concentration, air temperature, humidity and other settings.
NDIR (Non-dispersive Infrared) CO2 Sensor: professional detecting sensor to provide fast real-time measurement and ensure the high accuracy results.
CO2 Concentration Monitor: indoor air quality displayed in ppm with Good (0~800ppm), Normal (800~1200ppm), Poor(>1200ppm) indication.
Visible and Audible CO2 Warning Alarm: touch the ALARM Key to trigger the alarm function, once the CO2 concentration is exceed the preset value, it sounds di-di-di and backlight flashing to remind.
Datalogger Memory Function: once connect the CO2 monitor with the PC via the USB cable, the measured data can be saved unlimited.
Calibration Function: automatic baseline calibration (minimum CO2 level over 7.5 days) or manual calibration in fresh air.
Rechargeable Lithium Battery Power Supply: built-in with a 3.7V 1400mAh large capacity lithium battery that can be repeated charging.
Applications: widely used in homes, schools, offices, factories, vehicles and other places in the measurement of carbon dioxide content value.
