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.
