WTW CR 4200, Thermoreactor

Thermoreactor for parallel thermal digestion with 2x12 round cuvettes with 8 fixed / 8 user-defined programs with temperatures of up to 170°C and AQA. Features: • 2 digestion programs simultaneously. • 8 fixed programs for quick operation. • 8 user-defined programs from 25-170°C with high temperature digestion. • AQA/IQC with external temperature sensor. • Standardized digestion programs for the standard parameters COD, quick COD (148°C, 20 min.), total nitrogen, total phosphorus, TOC and heavy metals of galvanizing with automatic heating and switch-off. • 8 user-defined digestions at temperatures between 25-170°C can be programmed for special degradations and therefore also allow high temperature digestions. • Two different programs for 12 cuvettes each can be run at the same time. • You can use an external temperature sensor instead of a vial with data output to the PC/printer for analytical quality assurance (AQA). Specifications: • Cuvette shafts: 2x12 cuvette shafts for round cuvettes, 16 ± 0.2 mm outer diameter. • Reaction time setting: 20 min, 30 min, 60 min, 120 min via fixed programs. • Temperature setting: 25 - 170°C freely programmable; 100 °C, 120 °C, 148 °C, 150 °C via fixed programs. • Overtemperature protection: 190 °C ± 5 °C. • Regulating accuracy: ± 1 °C ± 1 digit. • Temperature stability: ± 0.5 K. • Energy supply: 230 VAC 50 Hz ± 15 % / optional 115 VAC 60 Hz ± 15 %. Delivery Contents: Thermoreactor for thermal digestion of up to 170°, 2x12 cuvettes for two programs at the same time, fixed and user-defined programs, AQA, 115/230V adjustable, country-specific power supply.
