Waterproof Use and Cleaning
Connect the probe correctly before cleaning the main unit. Follow the instruction manual for washing and alcohol wiping, and keep connectors clean and dry when changing probes. The S270WP-41 surface probe is not waterproof.
Choosing the Right Probe
- Food and sample penetration: select a stem diameter and length suitable for the sample.
- Deeper measurement points: compare the long-stem S270WP-03 and sleeve-type S270WP-21.
- Immersion measurements: consider the S270WP-31 within its −40 to 105°C range.
- Flat surfaces: use the S270WP-41 within its 25 to 200°C range and keep it dry.
