Systematic process of measuring temperature at multiple locations within a refrigerated space over time to identify temperature gradients, hotspots, and system performance.
Temperature Mapping (Pharmaceutical)
Comprehensive study to document temperature distribution within refrigerated space (cold room, vehicle) under defined operating conditions. Required for GDP qualification.
Temperature Profile
Graphical representation of temperature over time, showing fluctuations, excursions, defrost cycles, and door openings. Generated by data loggers and monitoring systems.
Temperature Uniformity
Consistency of temperature throughout a refrigerated space. High uniformity means minimal temperature gradient; low uniformity indicates significant temperature variation.
Temperature-Controlled Transport
Transport services using refrigerated vehicles to maintain product temperature during transit. Includes all temperature ranges from deep frozen to cool chain.
TETA (Transport Education Training Authority)
Definition: Transport Education Training Authority. The SETA responsible for skills development in the transport sector, including road freight, logistics, and warehousing operations. Why It Matters: TETA qualifications are nationally recognized for transport professionals. Proper training reduces accidents, product losses, and compliance issues. Skills development levy claims available. Relevant Qualifications:– National Certificate: Road Transport (various NQF levels)– Professional Driving qualifications– Logistics…
Thermal Conductivity
A material’s ability to conduct heat, measured in W/(m·K) (watts per meter-kelvin). Lower values indicate better insulation.
Thermal Mass
The ability of a material to absorb and store heat energy. Materials with high thermal mass (like water, concrete) resist temperature changes.
Thermal Shock
Rapid temperature change that can damage products, packaging, or equipment. Occurs when cold products are exposed to warm environments or vice versa.
Thermocouple
Temperature sensor consisting of two dissimilar metal wires joined at one end. When heated, generates a small voltage proportional to temperature, which can be measured and converted to temperature reading.
