CATALOG

COD, BOD, TSS water quality monitor for STP and ETP that provides digital sensor technology and covers Dissolved Oxygen, Total Suspended Solid(TSS), Liquid Density and Conductivity measurements. COD, BOD, TSS water quality monitor for STP and ETP adopts the pulse xenon lamp as light source and the ultraviolet optical fiber spectrometer as detector is capable for real-time gathering of absorption spectrum of water pollutants ranging from 200nm to 800nm and real-time analysis of the content of water pollutants by means of chemometric algorithm technology. COD, BOD, TSS water quality monitor for STP and ETP includes two parts: the control box and the probe. The control box is installed in the analysis cabin and the probe is submerged in the water and fixed by means of mounting bracket the two parts are connected via cable. The control box provides power supply to the probe and at the same time receives the measurement value from the probe and displays them on the interface.

FEATURES

Model: V.WATER – 8001

  • It Requires no reagents, so it can save operating costs and will cause no secondary pollution .
    • The Reponce is quick (about 2 seconds ). It is suitable for the occasion where high real time performance is required , such as industrial process analysis .
  • Free from the interference of chloride ion .
    • It Adopts full-spectrum measurement and chemo metric algorithm analysis ,Which in comparison with the simple dual wave ength background subtraction technology, can measure more parameters and is less likely to be influenced by the compositional change of waste water.
    • All Components are independently researched and developed
    • It adopts pulse blowing method to clean the pollutants on the two window surfaces.                               The Instrument probe in the water measures organics in the water by means of xenon lamp . The calculation of the spectrum obtained after each measurement will produce a measured value, which will be transmitted to the control box and displayed.                                                                                                                                            • Optical Fiber on the main Interface . One measurement only takes several dozens of seconds . Mean While ,in the interval of measurement , the instrument will be automatically cleaned to prevent contaminants from being deposited on the surface of the lens .
