Brief Introduction
CKT3800 series dry type temperature calibration furnace is easy to carry and easy to use. It is used in fast and reliable temperature calibration and is widely used in machinery, chemical, food, pharmaceutical and other industries.
At present, the existing field dry-type calibration furnaces have problems of slow heating and slow constant temperature, which causes users to take long time for each calibration. Our latest dry well furnaces adopts the most advanced heating principle design, featuring fast heating, fast constant temperature and fast cooling, which greatly improves the existing calibration efficiency.
Through reliable high-precision temperature control circuits and high-precision sensors, the accuracy is higher than that of other domestic manufacturers, and the technology has reached international standards.
