A variety of 10K sensors

A variety of 10K sensors (left to right): A basic strap-on sensor with a hole for mounting on a lug; two sizes of immersion sensors; and a plastic swimming-pool control sensor. Note the O-ring on the pool sensor—it is designed to be placed in a hole drilled in the PVC piping and serve as an immersion sensor when clamped to the pipe.
