Receiving Dock Thermometer Calibration Log

Weekly inspection log for calibrating receiving and prep thermometers using the ice slurry method to verify accurate temperature readings for food safety records.

Inspection Details

• Inspection date and time recorded
• Location identified
  Document the receiving dock, prep area, or other thermometer location being calibrated.
• Inspector name recorded
• Thermometer ID or asset tag recorded

Ice Slurry Setup

• Container filled with crushed ice and water slurry
  Ice slurry should be a mixture of crushed ice and water, not ice alone.
• Slurry fully surrounds thermometer probe during test
  Probe must be immersed in the ice slurry without touching the container sides or bottom.
• Ice slurry stabilized before reading
  Allow the slurry to stabilize before taking the calibration reading.
• Calibration reference temperature
  Expected ice slurry reference is 32°F (0°C).

Thermometer Accuracy Check

• Thermometer reading in ice slurry
  Record the displayed temperature after stabilization.
• Reading within acceptable tolerance
  Thermometer should read 32°F ± 2°F unless the manufacturer's specification is stricter.
• Thermometer adjusted or removed from service if out of tolerance
  If the thermometer is inaccurate, document adjustment, replacement, or removal from service.

Corrective Actions and Verification

• Corrective action documented for failed calibration
  Include adjustment, repair, replacement, or removal from service.
• Retest completed after adjustment or repair
  If the thermometer was adjusted or repaired, verify it was retested in ice slurry.
• Thermometer returned to service only if accurate
  Only calibrated thermometers within tolerance should be used for receiving and prep temperature checks.
