Chemical Oxygen Demand Water Quality Automatic Analyzer

  • Description:The C310 Chemical Oxygen Demand Water Quality Automatic Analyzer is a product independently developed by BESCIENT TECHNOLOGIES. It operates based on the principle of potassium dichromate high-temperature digestion oxidation spectrophotometry. After undergoing pretreatment, the water sample is oxidized by potassium dichromate under high temperature and high pressure conditions. The Chemical Oxygen Demand (COD) content is then quickly determined using a spectrophotometer. The principle employed by the instrument complies with standards such as the "Water quality - Determination of the chemical oxygen demand - Dichromate method" (HJ 828-2017) and the "Water quality-Determination of the chemical oxygen demand-Fast digestion - Spectrophotometric method" (HJ/T 399-2007).

● The instrument is small in size, easy to transport, and flexible to install, allowing one person to complete the installation

● The instrument can be used in a wide range of applications, including laboratories and mobile monitoring vehicles

● The instrument is modularized, with high maintenance efficiency, and maintenance can be completed with a screwdriver

● Low reagent consumption, reagent level monitoring and early warning, overall replacement of reagents, prompt customer notification for easy replacement of reagents

● Using a specific combination method, it has strong ability to mask chloride ions

● Remote operation and remote online software upgrades allow for quick updates to customer needs and reduce maintenance

● Detailed records of the time and number of times the instrument door is opened, which can be used in conjunction with video to prevent data falsification and tampering

● The entire piping system is made of corrosion-resistant materials, which reduces the failure rate, maintenance requirements and extends the service life

● Multiple measurement modes, flexible addition of trigger measurements according to external drainage, convenient monitoring of enterprise gap drainage


The analyzer is widely used for online automatic monitoring of water quality at stationary construction stations in river assessment sections, lakes, reservoirs/water sources, hydrology, and sea inlet monitoring.
