Question

which thermocouple probe would be used to check the temperature of a pot of soup? air surface immersion penetration

Explanation:

• Air probes are for air - related temperature measurements.
• Surface probes are for surface temperatures.
• Immersion probes are for liquids (but penetration is more specific for thick substances like soup).
• Penetration probes are designed to go into thick or semi - solid substances (like a pot of soup) to get an accurate internal temperature.

Answer:

Penetration
