Sludge Judge samplers come in different configurations to match your requirements. Choose a full assembly with three 5-ft (1.5-m) sections that screw together or customize the length with individual pieces. The bottom section has a ball valve that collects liquid upon submersion and seals when lifted. The middle section provides extension capabilities, and additional sections can be added. The top section includes a nylon rope for convenience. Each segment is marked in 1-ft (0.3-m) increments for accurate sludge volume measurement. The Basic Sludge Judge and Sludge Judge Ultra have a 3/4" (1.9 cm) diameter and hold about 3 oz (89 mL) per foot. The Sludge Judge Ultra also includes UV stabilization to protect against sun damage.
