■ Product Usage
The 44X-6T series micro melting point analyzer can be widely used in production testing, drug inspection, and other fields such as medicine, chemical engineering, textiles, and pharmaceuticals. It can also be used by chemistry departments in higher education institutions to analyze organic substances such as single crystals or eutectics, and to observe and determine the melting point temperature of crystals; Research on engineering materials and solid-state physics: Observing the physical changes such as deformation, color change, and tri state transformation of objects under heating provides a favorable detection method.
■ Product features
*The heating table adopts domestically leading embedded ceramic far-infrared radiation heating technology, which has excellent properties such as uniform heating, strong corrosion resistance, long service life, and good insulation.
*The temperature sensing device uses special imported high-temperature adhesive to directly bond the platinum thermistor that senses temperature with the stainless steel worktable, thus having the characteristics of high temperature control accuracy, simple structure, and strong corrosion resistance.
*The temperature control adopts LED digital four digit display and PID self-tuning timed alarm (to prevent the heating table from drying out for a long time due to forgetting to turn off the power after the experiment is completed). The panel type temperature controller with single-chip microcomputer technology has the characteristics of automatic temperature control and high temperature control accuracy.
