OM便携式紫外臭氧检测仪: 2B Tech has taken the next step in miniaturization of UV-based ozone monitors by developing the Personal Ozone Monitor or "POM". The POM has dimensions of 4 x 3 x 1.5 inches and weighs only 0.75 lb (340 g). It has a built in GPS so that ozone measurements may be logged continuously along with geographic location. By folding the optical path in the shape of a "U", it was *sible to achieve the same path length in the POM as in the Models 202, 205 and 106-L and thus h*e similar precision and accuracy (~2 ppb). Personal ex*ure monitoring for studies of health effects of air pollutants Health and safety monitoring at industrial sites using ozone Vertical profiling using balloons, kites, RPVs and light aircraft where space and weight are highly limited Long-term monitoring at remote locations where power is highly limited Urban arrays of ground-based detectors Specifications Measurement Principle UV Absorption at 254 nm Linear Dynamic Range 2.0 ppb to 10 ppm Resolution 0.1 ppb Precision (1σ; rms noise) Greater of 2.0 ppb or 2% of re*g Accuracy Greater of 2.0 ppb or 2% of re*g Limit of Detection (2σ) 4.0 ppb NIST-Traceable Calibration Yes Measurement Interval 10 s (Data *eraging options: 10 s, 1 min, 5 min, 1 hr) Flow Rate (nominal) ~0.8 Liter/min Flow Rate Requirement >0.5 L/min Baseline Drift <2 ppb/day<5 ppb/year Sensitivity Drift <1%/day<3%/year Measurement Time, Frequency 10 s, 0.1 Hz Response Time, * of Step Change 20 s, 2 points Averaging Times 10 s, 1 min, 5 min, 1 hr Data Storage 8,192 lines (10 s *g ~1 day; 1 min *g ~1 wk; 5 min ~1 mo; 1 hr *g ~1 yr) Ozone Units ppb, ppm, pphm, g m-3, mg m-3 Pressure Units mbar, torr Temperature Units °C, K T and P Corrected Yes Operating Temperature Range 0 to 50 °C Power Requirement;Supplied by battery or 110/220 VAC Power Pack 7-24 V dc, nominally 250 mA at 12 V, 3.0 watt External Battery 7.4 Volt, 1.6 amp hour, Lithium Polymer Battery, 5-8 hr Size 4.0 x 3.0 x 1.5 inches (10.2 x 7.6 x 3.8 cm) Weight 0.75 lb (0.34 kg) Data Transfer Baud Rate 19200 DewLine Yes GPS Yes System Includes POM Personal Ozone Monitor AC Power Adapter (100-240 VAC to 12 VDC) with Cou*y-Specific Plug Cigarette Lighter Adapter 7.4 V Lithium Polymer Battery Battery Charger Serial Port Cable USB Cable Zeroing Cartridge CD with Operation Manual, 2B Display Software and USB Driver Instrument Birth Certificate Calibration Data and NIST-Traceable Calibration Certificate One Year Warranty 标签：     上海市臭氧检测仪   上海市臭氧检测仪厂家
