Thermoreactors for easy digestion of standard parameters
Safe and easy operation with automatic heating and switch-off for standard digestions
• 12 round cells (16 mm)
• 8 pre-programmed settings including fast digestion for COD
• Easy, quick operation for standard parameters
The required temperatures and degradation times for the standard parameters are stored in every WTW thermoreactor. In addition, there are different options for self programming and cuvette numbers available.
CR 2200 allows standardi 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.
