New temperature sensors feature an epoxy-coated NTC thermistor in a metal housing. A metal clip on the outside of the housing lets the assembly quickly install onto a straight section of copper tubing from 38 Ω to 58-in. OD. The clip stays snug even after being removed and installed numerous times.
