1、CO2 Detector: The multifunctional CO2 detector accurately detects carbon dioxide gas in the environment using infrared light absorption principles. It accurately measures the current CO2 concentration, temperature, and humidity in the air, providing a clear understanding of indoor air quality. 2、Long Lasting and Convenient: Equipped with a built in 2600mAh li battery, the indoor CO2 meter supports continuous use for extended periods. Featuring a large TFT LCD screen, it displays temperature or data easily according to your preferences. 3、Wide Applications: With a hanging hole on the back, this portable CO2 detector can be conveniently mounted on the wall for easy viewing. Suitable for use in grow tents, plant rooms, offices, kitchens, basements, schools, and cars. 4、Extensive Data Recording: With the capacity to store up to 6000 sets of data and alarm settings, users can set parameters and view historical records directly from the device or computer. All recorded data can be downloaded and exported to a computer for analysis. 5、Versatile in Various Industries: CO2 is essential for photosynthesis in plants, making our CO2 detector widely used in farms to enhance crop yields. Proper air fertilization with CO2 also improves livestock health. In industrial settings, CO2 detectors are crucial for monitoring air quality in wastewater treatment, factories, workshops, clean rooms, and more.
