Temperature Mapping
Humidity Controlled Chamber: Performance qualification with temperature and humidity mapping on site. Temperature mapping consist of one cycle at any one temperature and humidity point for a 24 hours period. This is done to demonstrate the uniformity of temperature and humidity within the chamber is acceptable and that the samples within the chamber receive a uniform temperature and humidity condition. Data is collected in printed format from up to eight different points (i.e. six temperature points and two humidity points) within the chamber. Temperature uniformity is considered acceptable if the deviation is less +1oC of set temperature. Humidity uniformity is considered acceptable if the deviation is within + 3% of set humidity.
