Online hexavalent chromium meter,GeG-3052


#Online hexavalent chromium meter, #GeG-3052


GeG-3052 is online and automatic hexavalent chromium analyzer and it is an optical method heavy metal online analyzer designed according to national environmental protection standards. It is applied to the simultaneous online analysis of various heavy metal elements in surface water, industrial process water and industrial wastewater, and the measured heavy metal elements.

After mixing the water sample and the regulator, the hexavalent chromium reacts with the indicator to form a colored complex in the presence of an acidic environment and an indicator, and the analyzer detects the change in the color and converts the change into The hexavalent chromium value is output. The amount of colored complex formed is equivalent to the amount of hexavalent chromium.

Main Features

Unique design makes this product have lower failure rate, lower maintenance, lower reagent consumption and better performance than similar hexavalent chromium instruments

Select valve assembly: select reagent sampling timing.

Metering component: Accurate metering of reagents through visible photoelectric system, which overcomes the quantitative error caused by wear of peristaltic pump tube; at the same time, it realizes accurate quantification of trace reagents

Injection assembly: peristaltic pump suction under negative pressure, there is always an air buffer between the reagent and the pump tube to avoid corrosion of the pump tube

Sealed digestion component: high temperature and high pressure digestion system, speeding up the reaction process, overcoming the corrosion of corrosive gas volatilization of the open system

Reagent tube: It adopts imported new PTFE transparent hose with a diameter of more than 1.5mm, which reduces the probability of water sample clogging
