TG-300 Low-Temperature Differential Scanning Calorimeter (–40 to 600 °C)

The TG‑20 low‑temperature differential scanning calorimeter employs semiconductor cooling, enabling a temperature range from –40°C to 600°C to meet the testing requirements of various materials. It features an intelligent temperature‑control system and a bidirectional operation mode. Differential scanning calorimetry is a thermal analysis technique that measures the power difference between the sample and a reference material as a function of temperature under programmed temperature conditions. This instrument can accurately quantify the thermal effects—such as melting, crystallization, glass transition, curing, and decomposition—that occur during heating or cooling, thereby providing critical information for material performance evaluation, quality control, and research and development.

TG-300 Low-Temperature Differential Scanning Calorimeter (–40 to 600 °C)

Description

Product Introduction:

Differential scanning calorimetry is a thermal analysis technique that measures the difference in heat flow between a sample and a reference material as a function of temperature under programmed temperature conditions. It can accurately quantify the thermal effects—such as melting, crystallization, glass transition, curing, and decomposition—that occur during heating or cooling, thereby providing critical information for material performance evaluation, quality control, and research and development.
