The HCR-100 COD rapid digestion instrument is a heating device for rapidly measuring chemical oxygen consumption. Sample digestion pretreatment can be performed for COD, total phosphorus, total nitrogen, and other parameters. To ensure safe use and facilitate customer observation of the sample during the experimental process, a transparent digestion protective cover is provided. Prevent liquid splashing from causing harm to the human body.
This instrument can automatically complete the constant temperature timing time, with a time setting of 10-15 minutes. After the temperature constant time is reached, the instrument has an automatic sound alarm function and stops automatically without manual intervention. Small temperature drift and high constant temperature accuracy. It adopts PID temperature controller, time controller, fast heating speed, small temperature buffer, constant and uniform temperature, and is easy to operate. It is a new experimental instrument product. Compared with the current reflux device for determining chemical oxygen demand using potassium dichromate method, it has the advantages of small volume, water saving, electricity saving, and good constant temperature performance. Suitable for heating and rapid determination of chemical oxygen demand (COD), the obtained data corresponds perfectly to classical methods and can be widely used in industries such as environmental protection, higher education, medicine, health, food, tap water, chemical industry, sewage treatment, papermaking, petrochemicals, metallurgy, printing and dyeing, making COD measurement fast and economical.
