Fluke 80PT-25 Immersion Temperature Probe measurement tool

SKU CH-8M8Z-N1K1M

Measures temperature from -196 °C to 350 °C with a 4-inch, 316 stainless-steel thermocouple probe and 3 ft 4 in lead

  • Wide -321 °F to 662 °F range covers cryogenic to high-heat tasks
  • Type T thermocouple delivers accurate readings in air or liquids
  • 316 stainless steel sheath resists corrosion in harsh media
  • 3 ft 4 in cable allows convenient positioning during tests
  • 4 in probe length suits standard immersion applications

Immersion Temperature Probe

The Fluke 80PT-25 is a thermocouple immersion probe designed for measuring the temperature of air or liquids. It suits technicians and engineers who need a direct-contact sensor with a miniature connector for compatible instruments. The probe body is constructed from 316 stainless steel for corrosion resistance. Its 4-inch length allows insertion into pipes, tanks or ducts.

Measurement Range and Connection

This probe covers a range of -321 to 662 degrees Fahrenheit, which corresponds to -196 to 350 degrees Celsius. The miniature connector limits use to instruments that accept a mini thermocouple plug. The 3-foot-4-inch lead provides a fixed reach between the probe tip and the meter. Users must verify that their device supports a Type T thermocouple with this connector style.

Type T Thermocouple Element

The primary measuring element is a Type T thermocouple, which determines the probe’s accuracy and temperature behaviour. This specification is the single factor that decides whether the probe matches the input requirements of the measuring instrument. If the meter expects a different thermocouple type, the readings will be incorrect. The package includes instructions for proper use.

Questions about this item

Which Fluke immersion probe model should I choose for liquid temperature measurement?

The 80PT-25 is designed for both air and liquids with a 4-inch 316 stainless steel probe and 3 ft 4 in wire length, covering -321 to 662 °F.

What does the -321 to 662 °F range mean when I am measuring hot oil in a workshop?

It means the probe can safely read from cryogenic liquids up to typical hot-oil temperatures without exceeding its 350 °C upper limit.

What does the mini connector cap in practice for meter compatibility?

The mini connector fits Fluke meters that accept a miniature thermocouple plug, letting you plug directly into the T-type input.
