CR 2200 COD Heating and Dissolving Device (WTW, Germany)Product Introduction:

Heating reactors, also known as digesters, are necessary equipment for chemical reactions such as COD, total nitrogen, total phosphorus, etc. They can maintain the necessary high temperature for the reaction within a set time to ensure digestion. In the new heating reactor, the most commonly used temperatures and reaction times for wastewater analysis are stored in pre-set programs that can be directly selected. In addition, the new heating reactor pays more attention to safety requirements to ensure compliance with safety regulations. To prevent accidents, each heater is equipped with a safety cover as standard, which avoids splashing of high-temperature chemical reagents and accidental contact with high-temperature surfaces due to test tube rupture, and prevents burns. Each reactor is certified by GS, CE, and cETLus.

The new CR3200 and CR4200 heating reactors meet strict quality system requirements. They have a special verification function, and when an external temperature sensor (optional) is placed in the slot, it can be directly printed out with a printer or the data of the preset standard temperature and actual temperature can be obtained on a computer. This can not only monitor but also record the operating status of the instrument.
