Type-K Thermocouple Probe: Fluke 80PK-1 (750422)
The Fluke 80PK-1 (Part#: 750422) is a Type-K beaded thermocouple probe designed for general purpose temperature measurements. The product offers a fast response due to its exposed, low-mass beaded tip and features a Teflon-insulated lead and a miniature Type-K connector.
Technical Overview
- Type: K, Special Grade (Chromel vs Alumel)
- Beaded Tip: 0.04 inch
- Lead Insulation: Teflon
- Miniature Connector: yellow, Type-K with 0.312-inch pin spacing
For safe operation, the probe must not be used where voltages exceed 24 V AC RMS or 60 V DC. The Teflon cable is not suitable for immersion in liquids, and at temperatures above 260 °C, Teflon can release toxic fumes (refer to manufacturer's instructions).
Typical Applications
The Fluke 80PK-1 is used for general purpose temperature measurements with Type-K thermocouples and is intended for instruments that accept miniature Type-K connectors and have cold junction compensation. Its fast response time makes it suitable for applications where quick measurement of surface temperature is required.
