Thermoreactors

The right Instrument for the right Test !

Thermoreactors, also known as dry thermostats, are necessary for carrying out chemical digestions, e.g. for COD, total nitrogen, total phosphorus. They ensure that the digestion is carried out completely, as they maintain the necessary high reaction temperature throughout the whole of the defined period. In each of the new thermoreactors the most important temperatures and digestion times used in wastewater analysis are stored in easily selected digestion programs, such as the COD digestion at 148 °C for 2 h. In addition, you can program the CR 3200 and the CR 4200 to carry out your own individual digestions at other temperatures. For simultaneous digestions, such as for COD (148 °C) and total-N (120 °C), the CR 4200 is suited as the two thermoblocks can be controlled separately.

CR 2200 : 

The CR 2200 is the routine instrument for the digestion reactions required for the analysis of wastewater. All programs can easily be selected. A well-designed heating system means that the stability and accuracy of the set temperature are outstanding.

CR 3200 : 

The CR 3200 is the thermoreactor for a wide range of applications. Numerous determinations can be carried out in its 24 openings. The CR 3200 also impresses with the stability and accuracy of the set temperature thanks to the well-designed heating system. The temperature can be freely selected in 1 °C steps between room temperature (25 °C) and 170 °C. As you can enter 8 of your own temperature programs this means, for example, that you can store a similar program to the short-time COD determination (DIN 38 409 H43) with a 15 minute digestion at 148 °C as your own program. Test agent monitoring is possible with the CR 3200 by using the TFK CR Thermosensor (recommended accessory).

CR 4200 : 

The CR 4200 is ideally suited if different digestions have to be carried out simultaneously as the heating blocks can be controlled separately. For example, one heating block with 12 cuvettes can be used to carry out a COD digestion at 148 °C while the other one is carrying out the total-N digestion at 120 °C with a further 12 cuvettes. The CR 4200 also impresses with the stability and accuracy of the set temperatures, even when the blocks are be used at different temperatures, thanks to the well-designed heating system. The temperature can be freely selected in 1 °C steps between room temperature (25 °C) and 170 °C. As you can enter 8 of your own temperature programs this means, for example, hat you can store a similar program to the short-time COD determination (DIN 38 409 H43) with a 15 minute digestion at 148 °C as your own program. Quality assurance is possible with the CR 4200 by using the TFK CR Thermosensor (recommended accessory).

Qualiti Assurance :

Qualitiy assurance is constanly increasing in importance, even in the operational analysis sector. The CR 3200 and CR 4200 thermoreactors are both equipped with an external temperature sensor as a testing aid. This temperature sensor can be plugged into the interface in place of cuvette and the set and actual temperatures can be outputted either to a printer or a PC. This means that the function can not only be monitored, but also documented.
