The TS-3 and TSR-3 electric-powered tube and screw samplers are designed for sampling powders and granules from gravity flow locations. The TS-3 mounts on two sides of the chute and features a 1.5-inch OD stainless steel sample tube with a full-length sample slot opening and an internal stainless steel auger. These low-maintenance samplers require very little headroom, and adapt easily under hoppers or tanks. Optional heavy-duty sample tubes, drives and a variable-speed auger motor are also available.
