HMA-TCR Total Chromium Heavy Metal Analyzer

Product description
Technical indicators
-Measuring principle:
At a certain temperature and pressure, in an acidic solution, various valence chromium in the water sample is oxidized to hexavalent chromium. 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 the concentration of total chromium.
- typical application:
On-line monitoring of total chromium in surface water, industrial wastewater (such as electroplating wastewater), and inlet and outlet of sewage plants
-Instrument features:
● Low waste liquid. The amount of waste liquid is only 1.3L / month
● Low reagent consumption. No need to change reagents in one month
● Automatic range, automatic dilution. Both low-range and high-range modes
● Built-in high temperature digestion device
● Automatic backwash sample filter, automatically cleaned after each test
● Automatic calibration
● 5.7 ”color LCD touch screen
● Chinese menu
