Penetration
Use for immersion and air; however air response time will be slower than if using an actual air probe.

Chisel
Need chisel tip for surface temperatures. Penetration and/or air tips will not give an accurate surface reading.

Contact
Measures three times faster than chisel tip.

Needle
Use for immersion and semi-solids. Low mass, quick response, small diameter penetration
