5 In 1 Air Quality Monitor TVOC HCHO CO2 Detector Temperature Humidity Tester(Black)

1. Use high-precision temperature and humidity sensors to detect in real time and automatically refresh data.2. 1.9-inch clear color display, 240 x 280 resolution, HCHO, TVOC, CO2, temperature, and humidity are more intuitive and easy to read.3. Equipped with high-precision semiconductor sensors to accurately identify and capture different pollutants in the gas, and the real-time HCHO, TVOC, and CO2 gas concentrations are more accurate.4. Built-in highly sensitive smart chip to quickly detect air quality and ensure more accurate instrument detection.5. Equipped with air quality level classification function, 4 different color fonts correspond to different air quality levels, allowing you to understand the current air conditions more accurately and vividly.6. Compact body design, simple and stylish appearance, you can put it in your pocket and use it anytime and anywhere.7. The hundreds of vent holes reserved on the casing not only accelerate the convection between the air and the machine, improve the air flow rate for effective detection, but also provide better heat dissipation effect.8.
