Measures :CO2 and Temperature
Warning Carbon Dioxide Level
With NDIR (Non-Dispersive Infrared) Waveguide Technology Sensor

A portable meter that  measures CO₂ & air temperature. This is an ideal instrument for indoor quality (IAQ) diagnosis.

 

Poor indoor air quality is considered unhealthy because it causes tiredness, loss of ability to concentrate & even illness. IAQ monitoring & survey, especially in CO₂ level & air ventilation become widely applied in public areas such as offices, classrooms, factories, hospitals & hotels.

 

It uses NDIR (non-dispersive infrared) technology to ensure the reliablity and long term stability. It's useful in verifying HVAC system performance and air ventilation control.
