A handheld thermometer and container logger may disagree because their measurement points differ. Record what each device measures.
Why they differ
- An infrared thermometer may read a surface while a logger reads air or goods at its location.
- The logger's position inside the container can affect the result.
- Device IDs and verification details may differ.
Record both readings
Write each value with device ID, measurement point and time. Selecting one value hides the other device's information and how the difference arose.
Which value governs the decision
Confirm the decision method in contract and procedure. If unclear, ask quality; do not assume one reading type takes precedence.
Follow-up when readings differ
Follow the procedure's verification method. Record any additional method and result; local workflow sets the goods' status while the decision is pending.
The device itself is part of the record. Record the device ID and verification reference. If validity is uncertain, consult the responsible role before using the reading.
Where the logger sits
State logger position and measurement environment. Check device instructions and shipment procedure before comparing different setups.
