Especially for water treatment with SchlixX or SchlixX Plus, it is essential to determine water and sludge parameters. These include laboratory values as well as water, sludge and visibility depth. The latter allows important conclusions to be drawn about impairments caused by suspended organic matter or algae, for example. The sampling set makes it easy to take the necessary samples and determine the depths yourself. The set in the practical transport bag contains a sampler with telescopic rod, a telescopic measuring rail, a Secchi disc with measuring tape for determining the depth of visibility and five sample containers each for sludge and water.
