Model 202 Ozone Monitor?EPA Federal Equivalent Method (FEM)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. Flash card memory and a quiet, long-life internal air pump are now provided standard on the Model 202 Ozone Monitor. The Model 202 Ozone Monitor? is lightweight (5.5 lb., 2.5 kg.) and has a low power coumption (12V DC, 0.60 amp, 7.2 watt) relative to conventional itruments and is therefore well suited for applicatio such as:Vertical profiling using balloo, kites, RPVs and light aircraft where space and weight are highly limitedLong-term monitoring at remote locatio where power is highly limitedUrban arrays of ground-based detectoPeonal exposure monitoring for studies of health effects of air pollutantsEnvironmental health and safety monitoringLaboratory studies of the effects of ozone exposure on materials and organismsSee the Application Notes section below for some specific examples of published studies using the Model 202.The Model 202 has been designated by the EPA as a Federal Equivalent Method (FEM): EQOA-0410-190.Schematic DiagramOptioGPS for continuous logging of latitude, longitude, and altitude (for 10-s data mode and above)Bluetooth for wireless data tramissionRechargeable lithium-ion battery provides 12 hou of continuous operationExternal particle filteerial-to-USB adapterCold-weather package (pump, lamp heater for use down to -20 degrees C)High-altitude upgrade (pressure seor for use up to 25 km altitude)Low-power optionExtra-long-life internal air pump4-20 mA analog current outputRack-mount case configuratiopecificatioMeasurement PrincipleUV Absorption at 254 nmFederal Equivalent Method (FEM)Yes, EQOA-0410-190Linear Dynamic Range0 to 250 ppmResolution0.1 ppbPrecision (1σ; rms noise)Greater of 1.5 ppb or 2% of readingAccuracyGreater of 1.5 ppb or 2% of readingLimit of Detection (2σ)3.0 ppb (in 10-s measurement mode)NIST-Traceable CalibrationYesMeasurement Interval10 s (Data averaging optio: 1 min, 5 min, 1 hr)Flow Rate (nominal)~1 LiteminFlow Rate Requirement>0.6 L/minBaseline Drift< 2 ppb/day< 5 ppb/yeaeitivity Drift< 1%/day< 3%/yearMeasurement Time, Frequency10 s, 0.1 HzRespoe Time, ** of Step Change20 s, 2 pointsAveraging Times1 min, 5 min, 1 hrInternal Data Logger Capacity16,383 lines (10-s meas. = 1.9 days; 1-min avg = 11 days; 5-min avg = 1.9 mo;1-hr avg = 1.9 yr)SD Card Logger CapacityMinimum 2 GB (> 5-year capacity for 10-s measurement mode)Ozone Unitsppb, ppm, pphm, μg m-3, mg m-3Pressure Unitsmbar, torrTemperature Units°C, KT and P CorrectedYesOperating Temperature Range0 to 50 °C standard; optional -20 to 50 °C with low temperature modificatio (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 seorPower Requirement;Supplied by battery or 110/220 VAC Power Pack11-14 V DC or 120/240 V AC, 600 mA, 7.2 watt (6.2 watt with cell heater unplugged)Size3.5 x 8.5 x 11 inches (9 x 21 x 29 cm)Weight5.5 lb (2.5 kg); 2.8 lb (1.3 kg) without itrument caseAnalog Inputs for Internal Logging of Other Itruments3 Analog Inputs, 0-2.5 V; For example could log external T, P and RHData Outputs232, 0-2.5 V Analog, LCD Display: (Optional 4-20 mA Current, External USB Converter; request quote)Data Trafer Baud Rates2400, 4800, 19200Output RangesUser-Defined Scaling Factor in MenuDewLine?YesQuiet Long-Life Internal Air PumpYesFlow MeterYesOptioBattery; External Particle Filter; Serial-to-USB Converter; GPS (for 10-s data mode and above); 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 ConfigurationUpgradable to Model 205 Dual BeamYesSystem IncludesModel 202 Ozone Monitor with quiet, long-life internal air pumpAC Power Adapter (100-240 VAC to 12 VDC) with Country-Specific PlugFlash Card Memory for virtually unlimited data storageSD CardSD Card ReaderCigarette Lighter AdapterZeroing CartridgeOperation Manual on USB StickCalibration Data and NIST-Traceable Calibration CertificateItrument Birth CertificateOne-Year Warrantyhttp:lypeper.b2b168.com
