over a period of time may break the leads.
The bead type thermocouple probe is suitable for making temperature
measurements between –20 °C to 200 °C in PTFE compatible environments.
Do not use the bead-type thermocouple probe beyond the recommended
operating temperature range. Do not immerse this thermocouple probe in liquids.
For best results, use a thermocouple probe designed for each application — an
immersion probe for liquid or gel and an air probe for air measurements.
