Water Ozonizer Appliance Doas Technology UV Absorption Ozone Gas Analyzer

high water ozonizer appliance DOAS technology UV absorption ozone gas analyzerThe analyzer based on UV absorption spectroscopy and chemometric algorithms to measure SO2, NOx, O2, NH3, Cl2, O3, H2S and other gases concentration, with high accuracy, high reliability, fast response time, wide application and other characteristics, the indicators have reached or exceeded similar products, it can be widely used in environmental online monitoring, industrial control, security monitoring and other occasions.>>>Key FeaturesFull spectrum measurement and DOAS (Differential Optical Absorption Spectroscopy) algorithm, excelling in accuracy,  repeatability and anti-interference with moisture, dust.Modular design and no moving parts, higher reliability and easier maintenance.Pulse Xenon Lamp used as light source with over 10-year lifetime.The adoption of diode array sensor enables instant spectrum acquisition and rapid response.>>> Features and Benefits1. Analyzer uses the following optical technology platform to get the UV absorption spectrum, the technology platform consists of light source, gas chamber, fiber optics and spectroscopy (including the diaphragm, holographic gratings, linear array detector) and other optical components.2. UV-visible light emitted by the optical window into the gas chamber, is absorbed by the sample gas flowing through the measured gas chamber, carrying the tested sample gas absorbs light through the lens after gathering information coupled into optical fiber through the optical fiber transmission into the spectrometer splitting, sampling, to obtain the absorption spectrum of the gas.3. Use DOAS technology spectrum analysis, can analyze the concentration of the gas in the relevant component.>>> Measuring principle1) The light source emits ultraviolet beam which transfers to gas cell through optical fiber.2) After absorption by measuring gas, the light beam transfers through optical fiber to spectrometer.3) Being dispersed through the grating, and converted into electric signal by the array sensor, a continuous absorption spectrum of measuring gas is thereafter obtained.>>>Technology ComparisonItemUV Hot-Wet   MethodNDIRSpectral   RangeComplete and   continuous absorption spectra obtained through holographic grating and diode   array detectionNon Dispersive,   characteristic absorption spectra obtained through band-pass filterLinear   ResponseHigh wavelength   resolution secures linear responseband-pass   filtration compromises linear response SO2 LossHot-wet   prohibits SO2   dissolutionCondensation   inevitably causes SO2   lossSampling   SystemHeat tracing.   Requests only dust filtration, simple and no corrosiveCold-dry.   Requests dust filtration, condensation, water removal and corrosion proofZero   Calibration PeriodLong (DOAS   algorithm)ShortAnti-InterferenceThe combination   of complete & continuous absorption spectra, high wavelength resolution,   DAOS algorithm erases interference from dust, moisture and background gasesVulnerable to   moisture interferenceGas CellConnected by optical fiber,   easy to replace and low maintenance costComplex to replace and   maintenanceMaintenance  ReliabilityNo moving partsMoving parts   existed>>>Technical SpecificationsSO2, NOx AnalyzerTechnical   PrincipleUV-DOASInstallation   typeHot-wet    ExtractiveMeasurement   Range0~200ppm,    0~1000ppm, 0~3000ppmZero   Drift≤    ±2%F.S.Span   Drift≤    ±2%F.S.Accuracy≤    ±1%Response   Time(T90)≤    60sLinearity≤    ±1%F.S.O2  AnalyzerTechnical   PrincipleZirconia/ElectrochemicalMeasurement   Range0~25%Response   Time(T90)≤    60sLinearity≤    ±2%F.S.CO, CO2  AnalyzerTechnical   PrincipleNDIRInstallation   typeExtractiveCO   Measurement Range0~1000ppmCO2   Measurement Range0~20%Zero   Drift≤    ±2%F.S.Span   Drift≤    ±2%F.S.Accuracy≤    ±1%Response   Time(T90)≤    60sLinearity≤    ±2%F.S.Technical Data for UV gas analyzerProjectIndicatorsSO2 Detection rangeMin:0-50ppm,Max:0-100%,NO Detection rangeMin:0-50ppm,Max:0-100%,O2 Detection range0-25%, Electrochemical or zirconiaLinearity error≤±1%F.S.Repeatability≤1%Zero drift≤±1%F.S./ weekSpan drift≤±1%F.S./weekAmbient temperature5ºC~45ºCResponse time(T90)
