Product Details

-HMA-Cr6 Water Quality Hexavalent Chromium Heavy Metal Online AnalyzerMeasurement principle:

HMA-CR6 hexavalent chromium heavy metal analyzer adopts diphenylcarbazide spectrophotometric method as its hexavalent chromium determination method. In acidic solution, hexavalent chromium in water samples reacts with diphenylcarbazide (DPC) to form a purple red compound, which is measured by spectrophotometry at a wavelength of 540nm. Based on the initial color of the sample, which is different from the color after adding the color developer, a colorimeter is used for colorimetric measurement, and the concentration value of hexavalent chromium is finally calculated.

The main methods for determining hexavalent chromium in water include diphenylcarbazide spectrophotometry, fluorescence spectrophotometry, ion chromatography, atomic absorption spectroscopy, etc. The determination of hexavalent chromium in water by diphenylcarbazide spectrophotometric method is widely used by environmental monitors due to its sensitivity and good selectivity.

-Typical applications:

HMA-CR6 hexavalent chromium heavy metal analyzer is suitable for the determination of hexavalent chromium in surface water, industrial wastewater (such as electroplating wastewater), and sewage plant inlet and outlet water quality

-HMA-Cr6 Water Quality Hexavalent Chromium Heavy Metal Online AnalyzerInstrument features:

Low waste liquid. The amount of waste liquid is only 1.1L/month.

Low reagent consumption. No need to replace reagents for a month, greatly reducing the cost of hexavalent chromium determination.

Automatic calibration ensures that the instrument can measure more accurately.

Equipped with an automatic backwash sample filter, it automatically cleans after each test to ensure more accurate measurements and reduce manual maintenance.

● It has high and low range modes, can automatically switch ranges, and automatically dilute.

Chinese menu, more suitable for Chinese users.

Adopting a 5.7 "color LCD touch screen, making operation and display more intuitive.
