Product Description

The SINZEN Ultraviolet(UV) sensor  is an independently self-developed flue gas analysis product which is suitable for online gas analysis of environmental protection and industrial control sites. Based on Ultraviolet Absorption Spectroscopy and Differential Optical Absorption Spectroscopy, it adopts optical technology platform, and can conduct online analysis and measurement for gases including SO2, NO, NO2, H2S, Cl2 and NH3, etc. Under normal conditions, it is used to measure gas component of SO2, NOX and other gas components can be extended. One module can simultaneously carry out measurement for 5 gas components at maximum. The product owns features of high measurement accuracy and reliability, fast response and wide application.

Product Features

  1. The product adopts advanced online analysis technology with high accuracy, a low lower limit, and small temperature drift.
  2. Adopts Ultraviolet Absorption Spectrum Gas Analysis Technology and Chemometrics Algorithms. Water or dust does not affect the measurement accuracy. It has a low detection limit and small temperature drift.
  3. High range ratio (maximum 10:1). Strong gas chamber, low operation and maintenance cost.
  4. The gas chamber of the module is made of stainless steel, and the internal part does not require mirror polishing or gold plating. The gas chamber is very strong, with low cost and little effect from water and dust.
  5. The detector is connected to the gas chamber via optical fiber, which is convenient for replacement and achieves a low maintenance cost. The service life of the light source is up to 10 years.
  6. The light source adopts a pulsed xenon lamp, with long service life, good stability, and no preheating time. It achieves simultaneous measurement of NO and NO2.
  7. Carries out simultaneous measurement of NO and NO2. Then, the accumulation method obtains NOX, dispensing with the NO2 → NO converter. No optical moving parts, strong vibration resistance, and high measurement reliability. Modular design, good expandability, and convenient maintenance.
  8. Configured to produce diversified and customized products to meet all kinds of requirements.
