WDet-5000UVI Immersion UV Water Analyzer
Overview Of WDet-5000UVI Immersion UV Water Analyzer
WDet-5000UVI is the first full-spectrum (200-800nm) immersion UV portable water
quality analyzer at home. With features of the delicate and convenient
structure, plug and play, auto cleaning function, this online water analyzer
can be widely applied to measure indexes including COD, BOD, and turbidity in
surface water, underground water, and municipal sewage. Besides series of water
quality testing instruments in ZETIAN, there are also types of air quality
monitors for sale.
Technical Principle Of WDet-5000UVI Immersion uv water analyzer
The portable water analyzer adopts a pulse xenon lamp as the light source and
ultraviolet spectrometer as a detector, which can collect the absorption
spectrum of water pollution between 200nm and 800nm in real time. The water
pollutant content can be analyzed by this portable water quality analyzer in
real time through the chemometrics algorithm technology. The optical path is
shown as the following figure.
The spectral probe of the portable water analyzer can record a complete
spectrum between 200nm to 800nm (UV-visible light) and distinguish the spectrum
into 256 wavelengths to obtain "Spectral fingerprint". The water analyzer
equipment can monitor multiple parameters simultaneously through the
information contained in spectral fingerprint and compensate those parameters
aiming at possible cross-sensitivity. The relevance between measuring result
and laboratory result achieves high quality that simple optical instrument can
never obtain before.
Features Of WDet-5000UVI Immersion UV Water Analyzer
The portable water quality analyzer adopts a full spectrum (200-800nm) (UV-
visible light) measurement technology and chemometrics algorithm. Compared with
dual wavelength background deduction technology, portable water quality
analyzer can measure more parameters and be less affected by composition change
Our online water analyzer uses high-pressure gas to clean probe automatically,
or employ immersion electrical brush to clean.
Not required for reagent preparation; save operating cost and no secondary
ZETIAN portable water quality analyzer has fast response time(about 2s),
applied to occasions with high requirements for real-time.
Without interference by chloride.
