Type K Thermocouple Probe from FLUKE
This description is about the Fluke 80PK-3A (Part #: 874610), a Type K thermocouple surface probe designed for direct temperature measurement on flat or slightly convex surfaces. The probe's measuring junction is exposed to ensure direct contact between the probe and the measurement surface.Description
The Fluke 80PK-3A is a Type K surface probe with a 1 meter (40 in.) cable and miniature thermocouple connector. The probe is intended for connection to temperature measuring equipment with input for Type K thermocouples and a miniature thermocouple connector with cold reference junction compensation.
Key Features
- Measuring junction: exposed junction for direct surface contact
- Measurement: designed for flat or slightly convex surfaces
- Cable and connector: 40" (1 meter) cable with yellow mini-thermocouple connector
- Response time: typically 3 s on metal surface; max. 15 s for a 260 °C change
- Safety limitation: must not be used where voltage exceeds 24 V AC RMS or 60 V DC (risk of electric shock)
Typical Applications
- Used for measuring the temperature of flat or slightly convex surfaces by direct contact with the measuring junction.
- Can be used with any temperature meter that accepts Type K thermocouples and has a miniature connector and cold-reference compensation.
