Hexavalent chromium online monitoring instrument is a high-precision device used for real-time and continuous monitoring of hexavalent chromium content in water bodies. Its working principle is based on optical or electrochemical technology, and it is widely used in environmental protection, industrial production, water quality management and other fields. It is of great significance for ensuring water quality safety and controlling environmental pollution.
Hexavalent chromium online monitoring instrument is used for real-time monitoring of hexavalent chromium concentration in water bodies, and is widely used in environmental protection, industry and other fields. The common method is based on the diphenylcarbazide spectrophotometric method, in which hexavalent chromium in water samples reacts with diphenylcarbazide under acidic conditions to form a purple red compound. The instrument measures the absorbance of the compound at a specific wavelength (such as 540nm) and calculates the concentration of hexavalent chromium based on the proportional relationship between absorbance and hexavalent chromium content. In addition, there is an electrochemical sensor method that monitors the concentration of hexavalent chromium by undergoing redox reactions with specific electrodes.
Instrument Features
Real time monitoring: It can continuously and real-time monitor the hexavalent chromium content in water, without the need for frequent manual sampling and laboratory analysis, and can promptly detect changes in water quality.
High degree of intelligence: equipped with functions such as automatic zero adjustment, automatic calibration, automatic measurement, and automatic cleaning, reducing the difficulty and error of manual operation. It can also record and analyze data in real time, and automatically alarm when the concentration exceeds the preset limit value.
Diverse measurement methods: supporting manual measurement at any time, automatic timed measurement, automatic periodic measurement, etc., to meet different monitoring needs.
Application field
Water source monitoring: Monitor the concentration of hexavalent chromium in tap water, groundwater, rivers, lakes and other water sources to ensure the safety of drinking water.
Industrial wastewater treatment: Real time monitoring of hexavalent chromium content in industrial wastewater such as electroplating, metallurgy, and leather making, helping enterprises control the wastewater treatment process and ensure compliance with discharge standards.
Wastewater treatment plant monitoring: Monitor the concentration of hexavalent chromium in the inlet and outlet of the wastewater treatment plant, evaluate the treatment effect, and optimize operating parameters.
Emergency monitoring: In sudden environmental pollution incidents, quickly detect the hexavalent chromium content in water samples to provide data support for emergency response.
Scientific research experiments: Provide accurate data on hexavalent chromium content in fields such as chemistry, environment, and medicine to assist in the achievement of scientific research results.
