The meter measures CO2 level, air temp., dew point, wet bulb temp. and humidity(DP, WB, RH are for models 7755/77535) and is an ideal instrument for indoor air quality (IAQ) diagnosis. 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 is also suggested in regulations of industrial hygiene in some countries. (See Appendix) The portable CO2 meter uses NDIR (nondispersive infrared) technology to ensure the reliability and long term stability. It’s useful in verifying HVAC system performance and air ventilation control. Features: 1. Triple displays of CO2 level, temp. and humidity (7755/77535). 2. Stable NDIR sensor for CO2 detection. 3. Statistics of weighted average TWA (8 hours weighted average) STEL(15 minutes weighted average) 4. Backlight for working in dark area. 5. Audile CO2 warning alarm. 6. Battery and adaptor power supply (Optional). 7. Easy manual calibration on CO2 and humidity (RH for 7755/77535 only). 8. PC connect via RS232 port interface.
