SureGripTM Tapered

Temperature Probe

Instruction Sheet

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-26 SureGripTM Tapered Temperature Probe is
essentially a bead probe with a handle that can be used
as a surface probe. The stainless steel sheath allows the
bead to measure temperatures higher than bead probes
with flexible leads. The handle also allows you to apply
more focused surface pressure without having your hand
in close proximity to the source. The 40-inch (1-meter)
cable is terminated with a Type K miniature thermocouple
connector with 0.792-mm (.312-in) pin spacing. The
80PK-26 can be used with any temperature-measuring
instrument that is designed to accept Type K
thermocouples and has miniature connector input.
