Testing unit for water and sediment in redox-milieu, has redox milieu detector that is vertically pushed through entire depth of area to be tested, and permeable passive collector fixed at detector and surrounding horizontal directions

摘要

The testing unit has a redox milieu detector, which is vertically pushed through an entire depth of an area to be tested, and a permeable passive collector fixed at the detector, where the collector surrounds all horizontal directions. A permeable flow direction analyzer is fixed at the detector, and surrounds all vertical directions or the horizontal directions. The detector has a support structure with a woven polyester band, which is coated with a manganese dioxide pigment.
