摘要
该仪器采用液氮作制冷剂解决了对冷井进行等速降温的难题,采用等速降温和等速升温顺序操作,可同时测出样品的凝固点和熔点值.其测试温度范围在20℃至-80℃之间测试精度为±1℃.它具有用量小、快速简便和安全可靠等优点,适用于对火药和炸药的易燃易爆样品测试,在军工系统中有推广的价值.
A microthermal testing instrument is designed to meet the practical requirement. The instrument uses liquid nitrogen as refrigerant and can lower or raise temperature at constant speed. The solidifying points and fusing points of specimens can also be determined with the instrument.It is suitable for testing combustable and explosive samples with phase change temperatures between 20～80℃.
