Hash HT200S High Temperature COD Dissolver 165 ℃ Rapid Heating Explosion proof Design Water Quality Testing

Description :

  The HashHT200S high-temperature COD digester is a pre-treatment instrument designed specifically for high concentration chemical oxygen demand (COD), total chromium, and other water quality testing projects. This device accelerates the oxidation and decomposition process of organic matter in water samples through a high-temperature and high-pressure environment, solving the problems of long time consumption and low efficiency of traditional digestion methods. It is suitable for high-temperature digestion needs in environmental monitoring stations, sewage treatment plants, and industrial enterprise laboratories, ensuring the accuracy and consistency of detection data.

  The Hash HT200S high-temperature COD digester has excellent thermal performance parameters, with a maximum heating temperature of 165 ℃, meeting various stringent digestion requirements. The optimization of its heating system is significant, and it only takes 12 minutes to raise the temperature to 150 ℃, greatly reducing the waiting time for the experiment. The core components of the equipment are equipped with explosion-proof designed digestion tubes, combined with dual safety protection mechanisms for over temperature and over pressure, in compliance with laboratory safety operating standards, effectively preventing safety accidents caused by abnormal pressure or temperature control, and ensuring the safety of operators and equipment.

  In the selection of applications, the Hash HT200S high-temperature COD digester is particularly suitable for high concentration wastewater detection scenarios that require strong oxidation conditions. Compared with ordinary low-temperature digestion equipment, its advantage lies in a higher temperature upper limit and faster heating rate, which is suitable for treating industrial wastewater samples with complex components and difficult degradation. If the testing items only involve low concentration surface water and do not require high temperature and high pressure conditions, conventional digestion equipment can be selected; But for the determination of specific indicators such as total chromium and permanganate index, this model can provide a more stable reaction environment and avoid errors caused by incomplete digestion.

  When using the Hash HT200S high-temperature COD digester, it is necessary to strictly follow the operating procedures to load the digestion tube and ensure good sealing to prevent air leakage. In daily maintenance, it is necessary to regularly clean the heating holes and surface stains, check the sensitivity of safety valves and sensors, and ensure that the over temperature and over pressure protection functions are normal. It is recommended to perform air burning and cleaning after each batch of experiments to remove residual organic matter. Common faults such as slow heating are often caused by carbon buildup or poor contact in the heating module, and need to be promptly investigated; If there are cracks or deformations in the digestion tube, it should be replaced immediately. It is strictly prohibited to continue using it to ensure experimental safety and reliable data.
