	BOD Measurement System OxiDirect

The OxiDirect from Lovibond Tintometer provides accurate and direct display of BOD (Biochemical Oxygen Demand) values in mg/l for a user selectable measuring period from 1 to 28 days. The easy-to-handle, Mercury-free, environmentally-friendly instrument is being used internationally to determine the effects of domestic and industrial waste water on sewage plants and outflow points. The Lovibond sensor system OxiDirect is a 6 sample system that allows precise measurements of BOD based on the manometric principle. Manometric respirometers relate oxygen update to the change in pressure caused by oxygen consumption while maintaining a constant volume. Thanks to the modern integral pressure sensors, it is no longer necessary to use mercury for pressure measurements.

BOD Measurement System OxiDirect

Measuring ranges and sample volumes

The BOD level of a sample depends on the quantity of organic matter present, which can vary considerably. The Lovibond® BOD measuring system OxiDirect is therefore calibrated for the various sample volumes and the corresponding measuring ranges listed in the table below. The overall measuring range of the system is 0 – 4000 mg/l.

For all measuring ranges, BOD is shown directly in mg/l.
