The OxiTop®-i is a modern, easy to use instrument for BOD measurement (Biochemical Oxygen Demand). The duration can be defined between 1 and 7 days. The sample volume can be selected on the menu. The conversion into the corresponding BOD value will be automatic, error-free and convenient. A small LED show the actual operating condition of the head. The heads have a modern design, are available in two different colours with adjustable numeric sample ID allowing distinction between inlet and outlet.

Thermoreactors for the determination of COD, total nitrogen or total phosphorus, ensure complete digestion of the sample and maintain the necessary high reaction temperature throughout the defined period. The most important temperatures and digestion times are stored in 8 fixed, easily selectable digestion programmes. CR 3200 and CR 4200 can be used with optional TFK CR external temperature probe, which can be used as a testing aid. It can be plugged into the interface in place of a cuvette, the set and actual temperatures can be output to either a printer or a PC, so function can not only be monitored, but also documented. Suitable for 16 mm cuvettes.
