Fluke 80PK-25 Type K Piercing Thermocouple Probe

Product Description

The FLUKE 80PK-25 is a Type K piercing thermocouple probe designed for direct temperature measurement in gels, liquids, and soft to semi-hard materials. The probe features a grounded junction and a 316 stainless steel sheath measuring 4 inches in length with a 0.134-inch diameter, making it suitable for puncturing food products, soft compounds, and similar media. The straight PVC-coated cable terminates in a Type K mini connector for direct connection to compatible meters and data loggers. Response time is 3 seconds, and the operating range spans -320 degrees F to 1,500 degrees F (-196 degrees C to 816 degrees C). Licensed HVAC technicians, refrigeration techs, and food-service equipment professionals are the primary installers.

This probe is well suited for residential and light commercial service work where surface or immersion probes are not appropriate. Common applications include checking temperature in viscous fluids, gel-based materials, soft food products, and semi-hard compounds. The piercing tip allows the probe to penetrate the material surface without requiring a pre-drilled access point. The 316 stainless steel sheath provides corrosion resistance and is considered food-safe, making it appropriate for use in food-service and refrigeration applications.

Installation Notes

This probe is installed by HVAC technicians, refrigeration technicians, and instrumentation professionals. Before connecting or disconnecting the probe from an active meter circuit, verify the instrument is set to the correct thermocouple type to avoid measurement errors. Insert the piercing tip directly into the material being measured and allow at least one full response cycle before recording temperature. Do not exceed the rated temperature range of the probe or the connected instrument.
