HMA-TNI Total Nickel Heavy Metal Analyzer

Product description
Technical indicators
-Measuring principle:
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 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.
- typical application:
On-line monitoring of total nickel in surface water, industrial wastewater (such as electroplating nickel-containing wastewater), and inlet and outlet of sewage plants
-Instrument features:
● Low waste liquid. The amount of waste liquid is only 1.9L / month
● Low reagent consumption. No need to change reagents in one month
● Automatic range, automatic dilution. Both low-range and high-range modes
● Automatic backwash sample filter, automatic cleaning before and after each test
● Automatic calibration
● 5.7 ”color LCD touch screen
● Chinese menu
