GL-200 COD Ammonia Nitrogen Total Phosphorus Total Nitrogen Analyzer-Fornitore globale

3rd Floor, Building 2, Medical Equipment Industrial Park, Daxue Road, High tech Zone, Heze City, Shandong Province

product overview

The G38 total chromium analyzer is developed and improved based on the national authoritative certification method GB7466-87 "Determination of Total Chromium in Water Quality". It can quickly measure the concentration of total chromium in enterprise wastewater using colorimetric methods, advanced cold light sources, narrowband interference technology, and microcomputer automatic data processing. It directly displays and prints the concentration value of the sample. The device is equipped with a 4.3-inch full-color LCD screen and a guided detection mode, which reduces learning costs and allows users to easily and quickly get started.

application area

It can be widely used for water quality testing in research institutes, sewage engineering, water environment testing, petrochemicals, metallurgy and steel, biomedicine, food and dairy industry, wool textile printing and dyeing, electronic machinery, aquaculture, photovoltaics, leather, papermaking, and other fields.

Detection Principle

In acidic solution, trivalent chromium in the sample is oxidized to hexavalent chromium by potassium permanganate. Hexavalent chromium reacts with diphenylcarbazide to form a purple red compound. After improvement, the absorbance of iron ions at a specific light source wavelength is measured. The light source emits a light source signal to the sensor, which is processed by an ARM processor to directly feedback the sample concentration value, displayed in mg/L.
