Low Temperature Cooling Chambers for Charpy Impact Specimens - Charpy Impact Test Specimen Low Temperature Chamber - CHARPY-LTC80
Charpy Impact Test Specimen Low Temperature Chamber - CHARPY-LTC80
Charpy Impact Test Specimen Low Temperature Chamber - CHARPY-LTC80 is a state-of-the-art compressor refrigeration system developed in accordance with the requirements for low-temperature devices outlined in ASTM E23-2018, ISO 148, DIN EN 10045, and GB/T 229-2007 standards.
This chamber utilizes compressor refrigeration technology along with heat balance principles and a circulating stirring method to ensure uniform, automatic cooling and stable temperature control for test specimens.
The CHARPY-LTC80 is equipped with microcomputer technology, offering a digital temperature display, automatic temperature control, precise timing functions, and alarm features. With its fast cooling speed, large volume, and high temperature control accuracy, it is the ideal solution for cooling and heat preservation of material samples in low-temperature impact tests. This chamber is also versatile enough to be used for other low-temperature detection and testing applications, providing simple, safe operation and exceptional performance in accordance with international standards.
