Thomas Scientific Sludge Judge, 15 ft.
The Sludge Judge is designed to take accurate readings of settleable solids, 5% or less, in a variety of liquids, to any depth. It is ideal for sewage treatment plants, chemical plants, and food processing facilities - anywhere that accurate sample levels of settleable solids in noncaustic materials are needed. The unit holds approximately 3 oz. per foot (89 ml per 0.31 m). The Sludge Judge comes in 5 ft. (1.53 m) sections of 3/4" (1.90 cm) plastic pipe with screw-type connectors. The top section includes a nylon rope for raising and lowering the sampler. Individual sections can be combined as required to achieve the length needed. Do not use in liquids over 165°F (74°C). Sludge Judge is not autoclavable. A convenient cotton canvas carrying case that holds four sections, a cleaning brush, cleaning rod, and cotton strips are available. To use: Slowly lower the Sludge Judge to the bottom of the tank. The float valve opens, allowing materials to flow in. W
