- The CR 3200 has 2x12 cuvette slots, all of which can be opened with the same program. The CR 3200 also allows for eight custom programs with free selection of temperature up to 170 °C
Digestions of 24 round cells with pre-programmed and user-defined programs . In total 24 round cells (16 mm) in two seperate heating blocks using the same program
- 8 stored programs for easy and fast operation including COD fast digestion
- 8 user-defined programs from room temperature/25-170°C with high temperature digestion
- AQA/IQC with optional external temperature sensor for documentation
Programs for standard parameters COD including fast digestion (148°C, 20 min.), total nitrogen, total phosphorus, TOC and heavy metals of galvanizing with automatic heating and switch-off quick. User defined programs can be easily entered and stored from room temperature respectively 25-170°C to perform special digestions and thus allow high temperature digestion.
The very same program can be run for all vials at the same time; to perform two parallel digestion programs, the CR 4200 is the suitable choice. For the analytical quality assurance (AQA), the external temperature sensor TFK CR can be connected to the PC/printer instead of a round cell.
Programs for standard parameters
- 1: 148 °C for 120 minutes
- 2: 120 °C for 30 minutes
- 3: 120 °C for 60 minutes
- 4: 120 °C for 120 minutes
- 5: 100 °C for 60 minutes
- 6: 148 °C for 20 minutes
- 7: 150 °C for 120 minutes
- 8: 100 °C for 30 minutes
