Measure the temperature and superheat of smaller pipes with this pipe clamp temperature probe from Fluke.
Easy to install, the Fluke 80PK-8 is fully adjustable to clamp securely on a pipe and is suitable for use with pipes with diameter from 6mm to 35mm (1/4 inch to 1 3/8 inch). The probe can measure temperature from -29 to 149°C (-20 to 300°F).
This probe is terminated with an industry-standard type K thermocouple connector, allowing it to be used with a wide variety of thermometers, digital multimeters and other testers/meters which accept this input.
Note: the 80PK-8 is the smaller of Fluke's two pipe clamp temperature probes. Need a probe for larger pipes? Take a look at the 80PK-10 instead, which can be used for pipes with diameter from 32 to 64mm.
