Type-K Thermocouple Air Temperature Probe from Fluke
This Type-K thermocouple air temperature probe, Fluke 80PK-24 (Part#: 2098691), is designed for measuring temperature in air and gas. The description and technical data are taken from the manufacturer's instruction sheet and data sheet.
General Description
The Fluke 80PK-24 is an air temperature probe with a measuring tip protected by a perforated 304 stainless steel baffle and a 304 stainless steel sheath. The probe has a 1-meter (38 inches) cable terminating in a miniature Type K thermocouple connector with 0.792 mm pin spacing. The manufacturer provides an instruction sheet, and the product comes with a one-year limited warranty.
Documentation
Typical Applications
- Measuring temperature in air or gases (as stated in the manufacturer's instruction sheet).
Notes on Use
The probe should only be used with temperature meters that accept Type K thermocouples, miniature thermocouple connectors, and have cold junction compensation. Avoid exposing the baffle and sheath to halides or sulfides; immersion in liquid and use in reducing atmospheres or vacuum are not recommended. The maximum continuous temperature at the tip is 816 °C, while the maximum handle temperature is 125 °C.
