TEMP_RH_MAPPING
Storage and chamber temperature/humidity excursion monitoring with min-max envelope and mean kinetic temperature.
When to use it
Use TEMP_RH_MAPPING when a stability chamber, cold room, warehouse zone or shipping lane is monitored against a temperature and humidity specification, and both the excursion envelope and a mean kinetic temperature have to be reported for the period.
