  This product is a carbon dioxide detector, which can automatically detect carbon dioxide concentration, temperature and humidity, detect air quality, and protect your breathing health.

 Features:

 1. 3-in-1 detector: It can accurately detect carbon dioxide concentration, temperature and humidity, with stable performance and strong anti-interference ability.

 2. Non-dispersive infrared absorption: The carbon dioxide value tester adopts the non-dispersive infrared absorption principle, built-in automatic calibration algorithm, high sensitivity and low power consumption.

 3. PC mirror control panel: The display interface of the carbon dioxide detector adopts PC mirror material, which has good surface finish, good toughness, damage prevention and pressure resistance, and the display effect is clear and more intuitive.

 4. Simple operation: It adopts a single button design, which can be started and used by pressing it, and the CO2, temperature and humidity values can be displayed intuitively, avoiding complicated operations, fast, convenient and clear, and the readings are clear at a glance.

 5. Over-limit alarm: When the monitoring environment carbon dioxide concentration exceeds the standard, the reading of the carbon dioxide detector will increase, the indicator light will be red, and an alarm will sound.

 Note:

 1. Due to manual measurement, there will be a 1-2 mm error in the size. Thanks for your understanding.

 2. Due to different light conditions and different monitors, item color displayed in photos may be showing slightly different from real object.
