Definition: Systematic process of measuring temperature at multiple locations within a refrigerated space over time to identify temperature gradients, hotspots, and system performance.
Process:
1. Place calibrated data loggers at strategic locations (typically 9-25 points depending on space size)
2. Record temperatures over 24-72 hours under typical operating conditions
3. Identify warmest and coldest locations
4. Analyze results and determine maximum safe setpoint
5. Document findings and establish monitoring procedures
When Required:
- New cold room or vehicle commissioning
- GDP validation for pharmaceutical distribution
- After equipment modifications or repairs
- Annually for critical pharmaceutical operations
- When investigating temperature excursion problems
