80PK-22

SureGripTM Immersion

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-22 SureGripTM Immersion Temperature Probe is

designed for use in liquids or gels. The probe can also be used

as a general purpose temperature probe. The thermocouple

junction is protected from tip to handle by an Inconel sheath.

The 40-inch (1 meter) cable is terminated with a Type K

miniature thermocouple connector with 0.792-mm (0.312-in)

pin spacing. The 80PK-22 can be used with any temperature-

measuring instrument that is designed to accept Type K

thermocouples and has a miniature connector input.

Note

The 80PK-22 is not recommended for use in food or

beverage preparation. Use 80PK-25 for food

preparation.

Measurement Considerations

Instrument Compatibility

The 80PK-22 is 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-22 accuracy specification to determine the overall

accuracy of the combination.

Temperature Limitations

The probe tip of the 80PK-22 has a continuous temperature

rating of 1090 °C (1994 °F). However the opposite end of the

sheath nearest the handle should not be subjected to

temperatures greater than 125 °C (257 °F). This is the

maximum temperature limitation of the handle.

Media Limitations

The sheath material of the 80PK-22 is Inconel, an alloy of

chromium and nickel. It has excellent resistance to oxidation

and corrosion at high temperatures, but it should not be used

in the presence of sulfur above 537 °C (1000 °F).

Operation

Use the 80PK-22 as follows:

1. Connect the 80PK-22 to a compatible Type K temperature

measuring instrument using the miniature (0.312-inch pin

spacing) thermocouple connector.

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 tip of the probe, the

measuring instrument should display the ambient (room)

temperature. If the instrument does not read out properly,

refer to “Troubleshooting”.

Minimizing Thermal Shunting

The 80PK-22 Immersion Probe should be inserted at least 6.35

cm (2.5 in) into the environment to be measured to minimize

the shunting effect of the sheath.

Troubleshooting

With no heat or cold applied to the probe, the measuring

instrument should display the ambient temperature. If the

measuring instrument does not read out properly, try the

following:

1. Verify that the temperature-measuring instrument is

designed to be used with Type K thermocouples. The

temperature-measuring instrument should have a yellow

input connector and / or be marked with a “K” either on the

case or on the display.

2. Check for an open circuit indicator on the measuring

instrument. Some temperature measuring instruments

have a built-in circuit to indicate if the connected probe is

open. (All Fluke Temperature-measuring instruments have

this feature.) Refer to the owners manual accompanying

the measuring instrument to see if this feature is available.

Short the two input pins of the measuring instrument with

a piece of wire. If the instrument is functioning, it should

indicate the ambient temperature.
