G37 Hexavalent Chromium Tester-Fornitore globale

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

product overview

G37 hexavalent chromium analyzer, based on national authoritative certification methodGB7467-87The research and development of the "Determination of Hexavalent Chromium in Water Quality - Diphenylcarbazide spectrophotometric method" can quickly determine the concentration value of hexavalent chromium in enterprise wastewater. It uses colorimetric measurement, advanced cold light source, narrowband interference technology, and microcomputer automatic data processing to directly display and print 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, hexavalent chromium reacts with diphenylcarbazide to form a purple red compound. The absorbance of hexavalent chromium at a specific light source wavelength is measured, and the light source emits a light source signal to the sensor. The data is processed by an ARM processor and directly fed back to the sample concentration value, which is displayed in mg/L.
