Hexavalent Chromium Water Quality Online Monitor

  • Description:Under acidic conditions, hexavalent chromium reacts with the color reagent diphenylcarbazide to form a stable colored compound. This compound absorbs light at a specific wavelength. By measuring its absorbance, the content of hexavalent chromium in the water sample can be calculated. The method has excellent resistance to interference. Low concentrations of metal ions (such as iron, copper, and lead) present in the sample do not interfere with the measurement.

● The meter uses a common national standard method, which is mature and has strong anti-interference ability (various metal ions in water do not interfere with the measurement).

● The instrument is miniaturized and highly integrated, with a size only comparable to that of a computer mainframe, making it easy to transport and install

● Low reagent consumption and low waste liquid discharge, saving operating costs

● Platform and modular design, easy to maintain and quickly repair, high commonality of modules

● The entire piping system is made of corrosion-resistant materials and is designed for forward maintenance, which means low failure rate, less maintenance and longer service life

● Networked quality control function, remote standard sample verification, remote monitoring of instrument status and remote online software upgrades

● High-precision micro-metering ensures low reagent consumption, with only 1/4 to 1/10 of the reagents required by conventional counterparts for each test

● Automatic/manual/network remote measurement, cleaning and calibration

● Fault alarm, reagent level warning, power-on self-check, door-opening detection, power-off protection

● Imported touch screen, Chinese interface display, complete user rights management

● Supports 4-20mA, RS232, RS485 communication interfaces and MODBUS communication protocol



● Online monitoring of surface water (rivers, lakes)

● Online monitoring of drinking water (tap water and groundwater)

● Online monitoring of wastewater in industries, such as petrochemicals, mining, chemical industry, metallurgy, and electroplating

● Online monitoring of domestic sewage
