HMA-TCR Total Chromium Heavy Metal Analyzer/Online Analyzer

HMA-TCR Total Chromium Heavy Metal Analyzer/Online Analyzer
HMA
HACH HMA
In the HMA-TCR, chromium in all valence states in the sample is oxidized to hexavalent chromium under defined temperature and pressure in an acidic solution. Hexavalent chromium reacts with diphenylcarbazide (DPC) to form a purple-red compound, and spectrophotometric measurement is performed at 540 nm; the difference between the initial sample color and its color after adding the color reagent is measured colorimetrically, and the total chromium concentration is then calculated.

Typical Applications:

Surface water, industrial wastewater (such as electroplating wastewater), online monitoring of total chromium at the influent and effluent of wastewater treatment plants

Instrument Features:

● Low waste liquid. Waste liquid volume is only 1.3L/month

● Low reagent consumption. No reagent replacement needed for one month

● Automatic range switching, automatic dilution. Both low range and high range modes available

● Built-in high-temperature digestion device

● Automatic backwash sample filter, automatic cleaning after each measurement

● Automatic calibration

● 5.7” color LCD touch screen

● Chinese menu
