Whirl-Pak® Sample Collection Tools – Swings Samplers and Sludge Nabbers – are intentionally designed for those collecting samples from a horizontal flowing stream to make sample collection of liquids fast and easy. 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.
USA Manufactured
How to use a sludge judge: Slowly lower the Sludge Judge® to the bottom of the tank. The float valve opens, allowing materials to flow in. When the bottom has been reached and the pipe has filled to the surface level, tug slightly on the rope as the unit is raised. This sets the check valve, trapping the mixture inside. When the unit has been raised clear of the liquid, the amount of solids in the sample can be read using the 1 ft. (0.31 m) increments marked on the pipe sections. To release the material in the unit, touch the pin extending from the bottom section against a hard surface. This opens the check valve to drain the sample. Do NOT use for sampling ethanol or ethanol blended fuel.
