产品描述
Technical indicators
-Measuring principle:
In an acidic solution, hexavalent chromium and diphenylcarbazide (DPC) in the water sample form a purple-red compound, which is spectrophotometrically measured at a wavelength of 540 nm. Differently, the colorimetric method is used to measure the colorimeter, and finally the concentration value of hexavalent chromium is calculated.
- typical application:
Online monitoring of surface water, industrial wastewater (such as electroplating wastewater), and hexavalent chromium at the inlet and outlet of sewage plants
-Instrument features:
● Low waste liquid. The amount of waste liquid is only 1.1L / 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, automatically cleaned after each test
