AZ77597 Dual Function Temperature & Humidity Combo CO2 And CO Gas Leak Detector

Description

AZ77597 Dual Function Temperature & Humidity Combo CO2 And CO Gas Leak Detector
The portable CO
2
meter uses NDIR (non-dispersive infrared) technology to ensure the 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 CO
2
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.
Features:
Big LCD display with blue backlight to use in dark area
One touch to display CO
