The required temperatures and degradation times for the standard parameters are stored in every WTW Thermoreactor CR 2200. In addition, there are different options for self programming and cuvette numbers available.
The WTW Thermoreactor CR 2200 allows standard digestion with programs for COD, total nitrogen, total phosphorus, TOC and heavy metals of galvanizing. The high reaction temperature over a defined period of time ensures a complete digestion of the sample. For COD, an additional program for fast digestion (148°C, 20 min) is available.
