6. OPERATION MANUAL PORTABLE CO METER Model lt 5 5 pSENSE RH INTRODUCTION Thank you for purchasing this portable CO meter The meter measures CO level air temp dew point wet bulb temp and humidity DP WB RH are for model pSENSE RH 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 CO 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 Appendix The portable CO meter uses NDIR non dispersive infrared technology to ensure the reliability and long term stability It s useful in verifying HVAC system perform ance and air ventilation control Features e Triple displays of CO level temp and humidity pSENSE RH Stable NDIR sensor for CO detection e Statistics of weighted averages TWA 8 hours weighted average STEL 15 minutes weighted average Backlight for working in dark area Audile CO warning alarm Battery and adaptor power supply Easy manual calibration on CO and humidity RH for pSENSE RH only PC connect via RS232 interface MATERIAL SUPPLIED This package contains v Meter 4pcs AA
