5-in-1 Carbon Dioxide Detector, Indoor Air Quality CO2 Detector, Digital TVOC HCHO Meter, Temperature and Humidity Monitor, Backlight Tester (White)

【Easy to Use】CO2 measurement. The sensor module is high-precision, stable, and interference-resistant. The carbon dioxide concentration can be accurately displayed. It also displays humidity and offers three measurement modes. We recommend using it with a USB charger. 【Real-Time Detection】The CO2 sensor has a built-in high-performance chip and uses monitoring technology to report ventilation times. It captures pollution data more accurately and with low power consumption. The current generated during the electrochemical reaction is not limited by location or time, allowing for accurate CO2 measurement and supporting daily infection control and a comfortable environment. Easy-to-Read LCD Screen: The CO2 concentration meter features a large LCD screen with good visibility. It displays the CO2 concentration, temperature, and humidity in capital letters. These are also color-coded for easy reading at a glance. The screen brightness can be adjusted by pressing the left and right buttons on the power switch, making it a smart meter. 【Compact and Versatile Design】 Can be used as a desktop/wall unit. The CO2 concentration meter features a compact, small, lightweight design that is easy to carry and boasts a modern style. The CO2 monitor is suitable not only for homes but also for places where people gather, such as schools, hospitals, restaurants, shopping malls, storage facilities, poorly ventilated areas, manufacturing plants, luggage storage, greenhouses, etc. Advanced Detection Module: The air quality detector adopts an advanced electrochemical detection module with high accuracy, stable performance, high interference resistance, low power consumption, and a long lifespan. Compared to other products, our carbon dioxide detectors do not require calibration, can be tested immediately upon opening the package, and can detect CO2 accurately.
