Get the most out of your batch heating process by achieving and maintaining the best possible temperature uniformity.
How is Uniformity Measured? In order to determine the temperature uniformity inside an oven, temperature measurements must be taken at several locations. This is referred to as a temperature survey. A common benchmark for batch ovens is the standard nine-point test. Test thermocouples are placed near each corner of the work chamber, with another at the very center. After the oven is heated to the desired setpoint and soaked for a period of time, the nine points are measured and documented, typically with a chart recorder or datalogger. If any of the points are out of tolerance, the oven must be shut down and adjustments made to correct the problem.
