à¤Ã×èͧÇÑ´¡êÒ«¤ÒÃìºÍ¹ä´ÍÍ¡ä«´ì 7001 Carbon Dioxide Monitor The Telaire 7000 Series hand held monitors feature our patented absorption infrared technology. Accurately measures CO2 and Temperature while calculating real-time ventilation rates. The Telaire 7000 Series also offers data logging and RH data gathering capabilities when purchased with available accessories. Product kits include a power adapter, however, the unit may be operated up to 80 hours on 4 AA batteries (not included). Measurement Range: 0-4,000 ppm voltage output 0-10,000 ppm display Pressure Dependence: 0.13% of reading per mm Hg (Corrected via user input for elevation) Sensitivity: ± 1 ppm Repeatability: ± 20 ppm Temperature Dependence: ± 0.1% of reading per °C or ± 2 ppm per °C, whichever is greater, referenced to 25°C Accuracy: ± 50 ppm or 5% of reading, whichever is greater Annual Drift: ± 20 ppm typical Response Time: < 60 seconds for 90% of step change Warm-Up Time: < 60 seconds at 22°C Operating Conditions: 32 to 122° F (0-50°C) 0-95% RH, non-condensing Storage Temperatures: -40 to 140°F (-40 to 60°C) Calibration Interval: 12 months, offset adjustment using single gas at 0-1000 ppm CO2.
