The handheld Sludge Gun can be used to easily find sludge levels in lagoons, ponds, clarifiers, septic tanks or any other process where there is a liquid/sludge interface. These processes protect the environment. The design is portable, rugged and weatherproof. An audible tone that varies in volume and pitch indicates the sludge level.
