1. Intelligent carbon dioxide value tester The gas analyzer uses a semiconductor TVOC sensor to convert the carbon dioxide concentration, with stable performance, low consumption and long service life. Accurately detect carbon dioxide. The large screen displays power, carbon dioxide, temperature and humidity. 2. The product is small in size and easy to carry. The ventilation holes on the back can not only accelerate the convection between the air and the machine, achieve effective detection, but also provide good heat dissipation effects. 3. The product does not need to be calibrated, it can be tested after booting, and it can accurately detect carbon dioxide. It can be used in greenhouses, agricultural production, production warehouses, laboratories, households, etc. Size: 90*35*70mm Weight: 185g Color: black, white
