How to Use Sludge Judge:

1 Lower to the bottom of the tank
2 Float valve opens, allowing liquid to flow in. When filled to the surface level, tug slightly on the line as the unit is raised.
3 This sets the check valve, trapping the mixture inside
4 Read the amount of solids in the sample using the 1’ increments marked on the sections.
5 To release, touch the pin extending from the bottom section against a hard surface. This opens the valve to drain the sample.
