XWWarning

To avoid electrical shock, do not use this
probe when voltages exceeding 24 V ac rms
or 60 V dc are present. The probe tip is
electronically connected to the output
terminals.

Introduction

The 80PK-24 SureGripTM Air Temperature Probe is
designed for measuring the temperature of air or gases.
The measuring bead of the probe is protected by a
perforated 304 Stainless Steel baffle to prevent accidental
damage. The sheath material is 300 Stainless Steel. The
38-inch (1 meter) cable is terminated with a Type K
miniature thermocouple connector with 0.792-mm (.312-in)
pin spacing. The 80PK-24 can be used with any
temperature-measuring instrument that is designed to
accept Type K thermocouples and has a miniature
connector input.
