CO2 is not an air pollutant, but it can still have a negative effect on us when levels are too high.

When levels rise, we tend to get sleepy and have trouble focusing, and some people even develop headaches.

For this reason, it is important for occupants to have CO2 monitor to stay at a healthy level.

Product description

  • 【Professional】 This CO2 monitor can detect CO2, temperature and humidity. It has 2 CO2 detect modes, People and Plants. People mode detect if you are in a healthy range. Plants modes has 1-9 range corresponds different vegetable and fruits to detect whether the growing conditions of plants is good. It is usually used at where CO2 is generated on high levels, -Schools, Greenhouses,Office buildings,Factories,Hospitals,Hotels,Transportation lines.
  • 【Accurate】 This detector adopt NDIR(non-dispersive infrared)sensor what is a new type of infrared sensor, It works quickly, stably and won't be affected by temperature or other conditions than outdated Chemosensor. It’s detection accuracy is ± (50ppm+5% reading).
  • 【Data Logger】Built-in storage for continuous data logging, you can track trend data up to 7 days for co2 concentrations, temperature, humidity, and it display the Max &min value.
  • 【Automatic&manual calibration】 Offer 2 calibration model, manual calibration and automatic calibration. We has calibrated it manually in factory, and it can automatic calibrate during the detection.
  • 【Package include】CO2 monitor, USB cable ,User Guide. Please carefully read the User Guide when you receive the monitor, it has detailed direction for use, and if you have any question about this product please feel free to contact US, we will reply you with 24 hours.
