Abstract

A test element for a mobile water analyzing system includes a sample line and a key reagent disposed in the sample line. The sample line includes an inlet opening arranged at a first end, a pump port arranged at a second end of the sample line, an inlet section arranged between the inlet opening and the pump port, and a measuring section with at least one window arranged at an end of the measuring section. The inlet opening receives a water sample. The measuring section is arranged between the inlet section and the pump port and is coincident with a sample pathway.
