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.

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.
