(This digester can also be used for total phosphorus digestion, total nitrogen digestion, soil heavy metal digestion, etc.)

1、 Product Introduction:

The TC-12 COD digester/COD constant temperature heater is a classic method for analyzing wastewater using air condensation instead of water condensation to determine chemical oxygen consumption. It adopts a new type of temperature controller, with fast heating speed, constant and uniform temperature, easy operation, and is a new experimental instrument product. According to the testing conducted by the Quality Supervision and Inspection Center for Environmental Monitoring Instruments of the National Environmental Protection Administration, the results meet the requirements of the "GB 11914-89 Determination of Chemical Oxygen Demand in Water Quality - Dichromate Method".

TC-12 typeCOD digester/CODConstant temperature heaterAdopting digital settings, displaying heating temperature, automatically controlling heating temperature, and setting heating time. Fast heating speed, constant and uniform temperature, low power consumption, simple operation, stable and reliable performance, widely used for water quality testing in industries such as environmental protection, medical care, hygiene, food, tap water, papermaking, sewage treatment, printing and dyeing, petrochemicals, metallurgy, and universities.
