Hexavalent Chromium Online Analyzer:
The instrument is detected by colorimetric spectrophotometry. In an acidic solution of water, hexavalent chromium and diphenylcarbazide (DPC) produce a purple-red compound, which is spectrophotometrically measured at a wavelength of 540 nm. According to the initial color of the sample, the color is different from that after adding the developer The colorimetric method is used to measure the colorimeter, and finally the concentration value of hexavalent chromium is calculated and obtained.
 
Total Chromium Online Analyzer:
 
The instrument is detected by colorimetric spectrophotometry. Water samples are oxidized to hexavalent chromium in acidic solution and under certain temperature and pressure. Hexavalent chromium and diphenylcarbazide (DPC) produce a purple-red compound, and the spectrophotometric measurement is performed at a wavelength of 540 nm. According to the initial color of the sample, it is different from the color after the color developer is added. Method, and finally calculate and obtain the concentration value of hexavalent chromium.
 
Total copper online analyzer:
 
The instrument is detected by colorimetric spectrophotometry. The instrument uses high-temperature digestion of water samples to convert complex copper, organic copper, etc. into divalent copper ions. Then the divalent copper is converted into cuprous by the reducing agent hydroxylamine hydrochloride, and Yutongling is used as the coloring agent, and the cuprous ion reacts with Yutongling to produce a yellow-brown complex. The concentration of the complex is positively correlated with the total copper concentration in the water sample. Spectrophotometric measurement was carried out at a wavelength of 470 nm. According to the initial color of the sample and the color after adding the developer, the difference between the two was analyzed to analyze the concentration of the sample.
 
Total nickel online analyzer:
The instrument is detected by colorimetric spectrophotometry, the water sample is digested by high temperature, and the digestion reagent is added to the water sample. The sample is pumped to the high temperature digestion unit. The total nickel in the sample is digested into divalent nickel ions. Divalent nickel ions form an orange-brown colored complex with butadione oxime in an alkaline solution under the environment of an oxidant (ammonium persulfate). Spectrophotometric measurement was performed at a wavelength of 470 nm. According to the initial color of the sample and the color after adding the developer, the difference between the two was analyzed to analyze the concentration of the sample.
 
Total manganese on-line analyzer: The instrument is detected by colorimetric spectrophotometry. The sample is first added with digestion reagents and then pumped to the high-temperature digestion unit for high-temperature digestion. The total manganese in the sample is digested into divalent manganese ions. The divalent manganese ion of the sample reacts with formaldehyde oxime in a slightly alkaline solution and forms a brown colored complex. The spectrophotometric measurement is performed at a wavelength of 470 nm. According to the initial color of the sample, the color change after adding the developer Different degrees to determine the concentration of the analyzed sample.

  The instrument is designed to be used in medium dustiness, indoors, and at room temperature. The working environment temperature is recommended to be 10-40 ° C. Please do not install the instrument in direct sunlight, and no water drops can drip onto the instrument.
 
The design of the instrument can be installed on the wall.
For the size, please refer to the figure below (in mm). In the case of convenient on-site operation, install the instrument as close as possible to the sampling point, so that the water sample in the sampling pipeline can be fully updated for each measurement.
During installation, leave a space not less than 590mm ~ 890mm under the instrument, which is convenient for the connection of the pure water bucket and waste water bucket below to the instrument.
