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 80PT-25 SureGrip

Piercing Temperature Probe is

designed for use in liquids, gels, soft, and semi-hard

materials. The probe is made of 316 stainless steel, which

is suitable for food service use. The thermocouple junction

of the probe is protected from tip to handle by the stainless

steel sheath. The 40-inch (1-meter) cable is terminated

with a Type T miniature thermocouple connector with

0.792-mm (.312-inch) pin spacing. The 80PT-25 can be

used with any temperature-measuring instrument that is

designed to accept Type T thermocouples and has a

miniature connector input.

Measurement Considerations Instrument Compatibility The 80PT-25 is compatible with any temperaturemeasuring 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).

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 measuring instrument is designed to be used with Type T thermocouples. The measuring instrument should have a blue input connector and / or be marked with a “T”. 2. Check for an open circuit indicator on the measuringinstrument.
