2pcs Carbon Dioxide Detector Digital Temp Humidity CO2 Meter (White), 501 Original

Portable Carbon Dioxide Detector 3 in 1 Digital Temperature Humidity CO2 Meter with Backlit LCDDescription:It is equipped with a carbon dioxide sensor and a temperature and humidity sensor, which can measure the concentration of carbon dioxide in the air and the ambient temperature and humidity in real time. The measurement range of carbon dioxide concentration is 400-6000ppm. When the concentration is between 400-800, a green band is displayed. This means that the concentration of carbon dioxide in the air is low and the air is in a normal state. The green and yellow bands are displayed between 800 and 1200 at the same time, which means that the carbon dioxide concentration is higher. In this environment, it is harmful to the human body, showing green, yellow and orange stripes between 1200 and 1500ppm, indicating that the air is not good for the human body; if it exceeds 1500, the green, yellow, orange and red bands simultaneously show the carbon dioxide concentration Severely exceeded. When it exceeds 5000ppm, it may cause suffocation or even death. You should immediately open the windows to ventilateFeature:1. Three in one: It can be used as carbon dioxide concentration detection, thermometer and hygrometer at the same time.2.
