The WTW OxiTop®-i IS 6 Respirometric BOD Measuring System is a modern easy-to-use instrument for BOD measurement (Biochemical Oxygen Demand). The duration can be defined between one and seven days.

The sample volume can be selected in the menu. The conversion into the corrseponding BOD value will be automatic, error-free and convenient. A small LED informs about the actual operating condition of the head.

Equipment used to perform  BOD measurements.

BOD: Biochemical Oxygen Demand: It is the amount of oxygen that microorganisms, especially bacteria (aerobic or anaerobic), fungi and plankton, consume during the degradation of organic substances contained in the sample.

Features:

The Respirometric OxiTop® measuring system for BOD self check measurement with undiluted samples (DIN EN 1899 -2) – measuring ranges up to 4,000 mg/l BOD possible

No need to convert data – direct input of sample volume

Most reliable results – display of the curve at the head

Full information – interim values always available

BOD instrument for self-check with 6 measuring units, with direct display of the BOD value at the measuring head, universal power supply 100 to 240 VAC, 50/60 Hz; accessories. 6 OxiTop®-i measuring heads (3 x blue and 3 x grey), menu-operated, with backlit graphic LCD, control LED, operating buttons, for direct BOD readings, volume pre-selection, measurement duration between 1 and 7 days selectable, display of measuring curve, display of current readings.

COD

1x Thermoreactor

Brand:  WTW by Xylem

Code: CR 2200

Equipment used to perform  COD measurements.

COD: Chemical Oxygen Demand: It is the amount of oxygen needed to oxidize organic matter by chemical means and convert it into CO2 and H2O.

Thermoreactors for easy digestion of standard parameters

Safe and easy operation with automatic heating and switch-off for standard digestions

12 round cells (16mm)

8 pre-programmed settings including fast digestion for COD

Easy, quick operation for standard parameters

The required temperatures and degradation times for the standard parameters are stored in every WTW thermoreactor. In addition, there are different options for self programming and cuvette numbers available.

CR 2200 allows standardi digestion with programs for COD, total nitrogen, total phosphorus, TOC and heavy metals of galvanizing. The high reaction temperature over a defined period of time ensures a complete digestion of the sample. For COD, an additional program for fast digestion (148°C, 20 min) is available.
