TGH-SC COD Water quality on-line automatic monitor


Instrument is introduced
Tgh-sc COD water quality on-line automatic monitor is a new type of automatic monitor of chemical oxygen consumption (COD) of water quality developed by China green environmental protection company with independent intellectual property rights. The analyzer can work automatically and continuously according to the long-term unattended status set on site. According to the complexity of on-site test conditions, the corresponding pre-processing system can be selected to ensure the reliable test process, accurate test results and fully meet the needs of different occasions.
This product is suitable for waste water with cod in the range of 10~5000mg/L and chloride concentration less than 2.5g/L Cl-. According to the actual demand of customers, it can be extended to waste water with chloride concentration less than 20g/L Cl-. It is widely used in industrial pollution discharge wastewater, industrial process wastewater, industrial sewage treatment plant sewage, municipal sewage treatment plant sewage and other occasions.
The performance characteristics of
The principle of instrument testing adopts the national standard method, and the testing process fully conforms to the relevant standards of the industry
Simple maintenance and low running cost
