Overview
Hospitality Enviro Tech indoor air quality tester portable CO2 meter uses NDIR (non-dispersive infrared) technology to ensure reliability and long-term stability. It’s useful in verifying HVAC system performance and air ventilation control. Poor indoor air quality is considered unhealthy because it causes tiredness, loss of ability to concentrate, and even illness (ex. Sick Building Syndrome). IAQ monitoring and survey, especially on CO2 level and air ventilation become widely applied in public areas such as offices, classrooms, factories hospitals and hotels. It also suggested in regulations of industrial in some countries. CO is colorless, odorless, and tasteless gas which is slightly lighter than air. It is highly toxic to humans and animals.
