80PK-11
Type-K Velcro Thermocouple
Temperature Probe
Instruction Sheet
Introduction
The 80PK-11 is a Type-K Velcro Thermocouple Temperature
Probe designed for HVAC temperature measuring applications.
The 20 inch PVC cable terminates with a Type-K thermocouple
inside a 19.5 inch nylon Velcro cuff. The 80PK-11 can be used
with any temperature measuring instrument that is designed to
accept Type-K thermocouples and has a miniature connector
input. The 80PK-11 is not suitable for liquid immersion but can
work in humid to wet environments.
XWWarning
To avoid electrical shock, do not use this probe
when voltages exceeding 24 V rms or 60 V dc are
present. The probe tip is electrically connected to
the output terminals.

Measurement Considerations
Instrument Compatibility
The 80PK-11 is designed to be compatible with any temperature
measuring instrument that accepts Type-K thermocouples, has a
miniature thermocouple connector, and has cold reference
junction compensation. Accuracy of the temperature measuring
instrument must be considered along with the 80PK-11 accuracy
specification in order to determine the overall accuracy of the
combination.
Temperature Limitations
The 200 ºC (392 ºF) continuous temperature rating of the
80PK-11 is primarily determined by the Hytrel insulation. The
bead alone may be momentarily subjected to higher
temperatures without damage.
Media Limitations
Type-K Chromel-Alumel thermocouple wires are compatible with
clean oxidizing atmospheres.
Operation
WCaution
Repeated sharp bending can break the 80PK-11
lead. To protect the lead, avoid sharp bends,
especially near the connector.
Use the 80PK-11 as follows:
1. Connect the probe to a compatible Type-K measuring
instrument using the miniature thermocouple connector
(0.500 in pin spacing).
2. Turn on the measuring instrument and select the
appropriate range and scale.
3. Check the readout on the measuring instrument. With
no heat or cold source applied to the sensor, it should
display the ambient (room) temperature.
4. Wrap the probe firmly around the object you wish to
measure. The readout will give you the source
temperature.
