Wrap these probes around pipe, hose, or other tubular shapes to measure surface temperature. Pick the thermocouple type that best covers the temperature range you expect your surface to be. You should also make sure the thermocouple type you choose is compatible with the device you plan to connect it to. They’re often used with temperature controllers, thermometers, and data recorders.

These thermocouples are manufactured to conform to ASTM E230 for accuracy. Accuracy is how far off the reported value is from the actual temperature.

Hose-clamp probes require a slotted screwdriver, hex nut driver, or wrench to tighten the screw.

Hook and loop probes can be installed without tools, so they’re faster to attach and remove than hose-clamp probes. They adjust to fit around diameters up to 4''.

Connect thermocouple wires without soldering or splicing. The terminals on these terminal blocks are made from same materials as thermocouples to ensure no signal is lost. Also known as barrier strips, they shield connections from each other to keep them neat and minimize the chance of short circuits. Choose a terminal block that matches your thermocouple type. You should also make sure the equipment you’re connecting it to is also compatible with the same thermocouple type.

For easy wiring, each end is labeled positive or negative. Mount these terminal blocks to a panel or machine using the mounting holes.

Connect thermocouples and RTDs to extension wire and instrumentation. These terminal blocks mount inside a connection head and work with any thermocouple or RTD probe type. Choose one with enough circuits to accommodate your probe. Make sure to connect extension wire that matches your probe type.
