Measurement Considerations
Instrument Compatibility
The 80PT-25 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 80PT-25 accuracy specification to
determine the overall accuracy of the combination.
Temperature Limitations
The tip of the 80PT-25 has a continuous temperature
rating of 350 °C (662 °F). However the opposite end of the
sheath nearest the handle should not be subjected to
temperatures greater than 125 °C. This is the maximum
temperature limitation of the Hytrel handle. See Food
Service Limitations.
Exposure Limitations
The sheath material of the 80PT-25 is stainless steel. It
should not be exposed to halides or sulfides.
Food Service Limitations
The 316 stainless steel probe is suitable for contact with
hot or cold foods within the specified temperature range of
the probe. However the handle is made of Hytrel 5556
which is suitable for repeat food contact only under the
following conditions: food temperature under 65 °C
(150 °F), food alcohol content under 8 %. Food may be
wet, dry, or fatty. Also, the cable should not come in
contact with food.
Operation
Use the 80PT-25 as follows:
1. Connect the 80PT-25 to a compatible Type T
measuring instrument using the miniature (0.312 inch
spacing) thermocouple connector.
2. Turn on the measuring instrument, and select the
appropriate range and scale.
3. Check the read out on the measuring instrument. With
no heat or cold source applied to the bead, the
measuring instrument should display the ambient
(room) temperature. If the instrument does not read
out properly, refer to “Troubleshooting”.
Measuring Technique
The 80PT-25 should be inserted at least 31.75 mm
(1.25 in) into the substance to be measured to minimize
the shunting effect of the sheath.
