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.
