Temperature Mapping
Cooling Incubator : Performance qualification with temperature mapping on site.
Performance validation test consist of one cycle at any one temperature point for 8 hours period. This is done to demonstrate the uniformity of temperature within the chamber is acceptable and that the items within chamber receive a uniform temperature condition.
Data is collected in printed format from up to six different points within the chamber.
Temperature uniformity is considered acceptable if the deviation is less ±1ºC of set temperature.
Note: Every OSWORLD Cooling Incubator is validated prior to dispatch at the factory. Those customers who do not require on site mapping may request for FREE copy of factory mapping cycle data sheet.
