Review on 🌡️ Klein Tools 69140 K-Type Thermometer: Accurate HVAC Pipe Temperature Clamp, Measures -4 to +212°F by Brandon Daughenbaugh

I bought this as an inexpensive tool in the meantime until I got my hands on a digital manifold with pipe clamps. It does the job, but doesn't always make good contact. The biggest problem is the weak cable and plug. The pins are easy to bend (yellow connector) and the K-type male adapter socket is not very resilient. After a few unwanted jerks in normal use, the contact loosens and no longer has firm contact with the pins of the clamping fork. It is recommended to connect the two forks together to make them a single unit that cannot be separated.
