ZN-2COWT 6 In 1 PM2.5 Infrared Sensor CO2 Formaldehyde TVOC Temperature Humidity Detector Features: 1. It adopts excellent electrochemical detection module, which has high accuracy and stable performance, and can accurately detect carbon dioxide value. Large screen design, measurement data at a glance 2. Using semiconductor and infrared detection technology, real-time refresh once per second 3. Using superior electrochemical detection module, high accuracy, stable performance, can accurately detect carbon dioxide 4. Strong anti-interference ability, low power consumption and long service life 5. The product does not need to be calibrated, it can be detected when it is turned on, and can accurately detect carbon dioxide 6. Wall-mounted design, suitable for more scenes, more practical 7. There are hundreds of ventilation holes on the back of the shell, which can not only accelerate the convection between the air and the machine, so as to achieve effective detection, but also provide a good heat dissipation effect 8. Wide application: agricultural planting, greenhouse vegetables, production warehouse, material processing, home interior decoration, etc. 9. 6 in 1: PM2.5, CO2, TVOC, HCHO, formaldehyde, temperature and humidity 10.
