Model 202 Ozone Monitor The 2B Technologies Model 202 Ozone Monitor is designed to enable accurate and precise measurements of ozone ranging from low ppb (precision of ~1.5 ppb) up to 250,000 ppb (0-250 ppm) based on the well-established technique of absorption of UV light at 254 nm.? The Model 202 Ozone Monitor is lightweight (5.5 lb., 2.5 kg.) and has a low power consumption (12V DC, 0.60 amp, 7.2 watt) relative to conventional instruments and is therefore well suited for applications such as: 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 Personal ex*ure monitoring for studies of health effects of air pollutants Environmental health and safety monitoring Laboratory studies of the effects of ozone ex*ure on materials and organisms Flash card memory and a quiet, long-life internal air pump are now provided standard on the Model 202 Ozone Monitor. The Model 202 has been designated by the EPA as a Federal Equivalent Method (FEM):?EQOA-0410-190. Options GPS for continuous logging of latitude, longitude, and altitude Bluetooth for wireless data transmission Rechargeable lithium-ion?battery provides 12 hours?of continuous operation External particle filter Serial-to-USB adapter Cold-weather?package (pump, lamp heater for use down to -20 degrees C) High-altitude upgrade (pressure sensor for use up to 25 km altitude) Low-power option Extra-long-life internal air pump 4-20 mA analog current output Rack-mount *e configuration Specifications Measurement Principle UV Absorption at 254 nm Federal Equivalent Method (FEM) Yes, EQOA-0410-190 Linear Dynamic Range 0 to 250 ppm Resolution 0.1 ppb Precision (1σ; rms noise) Greater of 1.5 ppb or 2% of re*g Accuracy Greater of 1.5 ppb or 2% of re*g Limit of Detection (2σ) 3.0 ppb (in 10-s measurement mode) NIST-Traceable Calibration Yes Measurement Interval 10 s (Data *eraging options: 1 min, 5 min, 1 hr) Flow Rate (nominal) ~1 Liter/min Flow Rate Requirement >0.6 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 1 min, 5 min, 1 hr Internal Data Logger Capacity 16,383 lines (10-s meas. = 1.9 days; 1-min *g = 11 days; 5-min *g = 1.9 mo; 1-hr *g = 1.9 yr) SD Card Logger Capacity Minimum 2 GB (> 5-year capacity for 10-s measurement mode) 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 standard; optional -20 to 50 °C with low temperature modifications (pump and lamp heater cold-weather package) Operating Altitude Range ~0-13.5 km (150-1,013 mbar) standard; optional ~0-25 km (30-1,013 mbar) with upgraded pressure sensor Power Requirement; Supplied by battery or 110/220 VAC Power Pack 11-14 V DC or 120/240 V AC, 600 mA, 7.2 watt (6.2 watt with cell heater unplugged) Size 3.5 x 8.5 x 11 inches (9 x 21 x 29 cm) Weight 5.5 lb (2.5 kg); 2.8 lb (1.3 kg) without instrument *e Analog Inputs for Internal Logging of Other Instruments 3 Analog Inputs, 0-2.5 V; For example could log external T, P and RH Data Outputs RS232, 0-2.5 V Analog, LCD Display: (Optional 4-20 mA Current, External USB Converter; request quote) Data Transfer Baud Rates 2400, 4800, 19200 Output Ranges User-Defined Scaling Factor in Menu DewLine Yes Quiet Long-Life Internal Air Pump Yes Flow Meter Yes Options Battery; External Particle Filter; Serial-to-USB Converter; GPS; Bluetooth; 4-20 mA Current Output; Cold-Weather Package (pump, lamp heater); High-Altitude Upgrade; Extra-Long-Life Internal Air Pump; Low-Power Option; Rack-Mount Case Configuration Upgradable to Model 205 Dual Beam Yes System Includes Model 202 Ozone Monitor with quiet, long-life internal air pump AC Power Adapter (100-240 VAC to 12 VDC)?with Cou*y-Specific Plug Flash Card Memory for virtually unlimited data storage SD Card SD Card Reader Cigarette Lighter Adapter Zeroing Cartridge Operation Manual on USB Stick Calibration Data and NIST-Traceable Calibration Certificate Instrument Birth Certificate One-Year Warranty 標(biāo)簽： 2B代理 臭氧檢測(cè) Mode ? 2B代理 臭氧檢測(cè)儀 Model 202 ? 長(zhǎng)沙市2B Technologies ? 長(zhǎng)沙市2B Technologies廠家
