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
