Professional equipment and tools are essential for calibrating the temperature uniformity of heat treatment furnaces. High-precision temperature sensors are the core, with common ones including thermocouples and resistance temperature detectors, which can accurately sense temperature changes at different positions inside the furnace and provide an accurate data basis for calibration.
The data acquisition system is responsible for collecting and storing the temperature signals transmitted by the sensors in real time. It has multi-channel acquisition functions and can process the data of multiple sensors simultaneously, and it should also have a high sampling frequency to ensure that no critical temperature information is missed.
In addition, some auxiliary tools are needed, such as fixtures for fixing the sensors to ensure their stable placement inside the furnace; and calibration standard sources, such as constant temperature baths, which are used to periodically verify the precision of the sensors to ensure the reliability of the entire calibration process. Having these complete equipment and tools is a necessary condition for achieving precise calibration.
