CEM Rechargeable Carbon Dioxide Detector Lithium Battery Operated Electric High Precision CO2 Concentration Monitor

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(℃/℉ 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.
