WTW Thermoreactor CR 3200
Thermal reactor for COD and thermal digestion, up to 24 cuvettes using a program setting, 8 fixed and 8 adjustable programs with free choice of temperature to 170 ° C, 115/230V. Optional Accessories: External test sensor TFK CR for AQA - temperature monitoring.Thermoreactors
are required for the determination of COD, total nitrogen or total phosphorus. They ensure complete digestion of the sample, as they maintain the necessary high reaction temperature throughout the defined period. In each of the WTW thermoreactors, the most important temperatures and digestion times are stored in 8, easily selectable digestion programs. In addition to these 8 fixed standard programs, CR 3200 and CR 4200 thermoreactors allow you to store 8 of your own user-defined programs. Suitable for 16 mm cuvettes.
- Programs for routine tests
- Rapid digestion for COD
- Quality assurance with testing sensor (optional)
New programs for COD
For COD digestion, programs according to various international standard methods are available. On demand of many customers, a rapid digestion for 20 minutes at 148 °C (298.4 °F) is provided, as this timespan has proven to be sufficient for many applications. All reactors have timer functions. All reactors display when the reaction temperature is reached.
Along with superior safety, all WTW thermoreactors optimize the heat transmission between the heating block and cuvettes. The safety hood prevents chemicals from splashing in the event of a broken cuvette, a covering provides protection from contact with the heating block surface.
