These figures apply to the standard probe combination. Check the selected probe specification when using another model.

Temperature and Time Checks

Three temperature/time alarm settings support repeated checks within a HACCP procedure. Configure the target and holding time to suit your process. The instrument signals completion with a buzzer and LED.

Serial Number and Calibration Display

The startup display shows the unit serial number and, where recorded by Sato following recalibration, the calibration year and month. Users cannot enter this date themselves. Ask Seacom about calibration documentation for the thermometer and selected probe.

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.
