Muffle Furnace Manufacturers in Gujarat Brand: Hema Calibration of a muffle furnace is essential to ensure accurate and consistent results. Over time, the temperature sensors and controllers may drift, leading to inaccuracies in the heating process. Regular calibration helps maintain the furnace’s performance and ensures that it delivers the required temperatures. Calibration involves using a reference temperature source, such as a thermocouple, to compare and adjust the furnace's readings. Routine calibration is important for applications where precise temperature control is critical, such as in research or quality control processes.
