Get more accurate readings by using the right tip for your thermometer:
- Penetration: Use for immersion and air; air response time will be slower than if using anactual air probe.
- Chisel: Need chisel tip for surface temperatures. Penetration and/or air tips will not givean accurate surface reading.
- Air: Samples air temperatures three times faster than penetration or contact tips.
- Contact: Measures three times faster than chisel tip.
