Measuring device for detecting traces of oil in water

摘要

In the measuring device for detecting traces of oil in water, sample water and pure water as a reference medium alternately flow through the same cell (9), which is part of an IR absorption measuring device; upstream of the cell is a water metering section (1) with three bores (2, 3, 4) which are arranged roughly in a T or Y shape with respect to one another. The invention achieves a substantially improved sensitivity as a result of the fact that the cross section of the bores (2, 3) conveying the sample water (6) and pure water (7) is greater than the cross section of the bore (4) of the water metering section (1) facing the cell (9) (Figure 2). <IMAGE>
