Temtop C10 CO2 Monitor, Air Quality Monitor, Indoor Carbon Dioxide Detector, Tester for CO2, Temperature and Relative Humidity

Why CO2 As EPA claims that good ventilation is important to help protect people from COVID-19 and for healthy indoor environments in general. Carbon dioxide (CO2) concentrations indoors can provide information about ventilation and reduce the risk of virus transmission in indoor spaces.

Smart Self-calibration: Temtop combines our embedded algorithms and Sensirion ASC algorithm, allows the CO2 sensor to dynamically shift its CO2 reading by a constant, which helps your monitor to sustain a better performance under various scenarios.

Easy to Use & Read: Just use one single button to realize ON/OFF, Fahrenheit and Celsius switching. With a 3 color-coded LED indicator, it can be easily understood without any instructions - Green (Good), Yellow (Moderate) and Red (Unhealthy).
