1、 Product Introduction:

The TC-12A COD constant temperature heater (COD digestion instrument) 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 for measuring chemical oxygen consumption. The TC-12A COD constant temperature heater has been tested by the Environmental Monitoring Instrument Quality Supervision and Inspection Center of the National Environmental Protection Administration, and the results meet the requirements of the international standard method ISO06066-86.

The TC-12A COD constant temperature heater adopts digital setting, displays heating temperature, automatically controls heating temperature, and can set 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.

2、 Technical features:

1. The TC-12A COD constant temperature heater adopts digital temperature control, and the time can be set arbitrarily, making it easy to operate

2. Automatically calculate the heating reflux time, and when the heating reflux time reaches 2 hours, the instrument will automatically shut down.

3. Small temperature drift, energy-saving, water-saving, low power consumption, fast heating speed.

4. Made with new digital temperature control devices and processing technology, each heating hole is uniformly and temperature controlled.

5. The surface of the instrument is treated with the latest anti-corrosion technology to increase its service life.

6. Sewage cooling makes operation more convenient and energy-saving.
