Scope of Application

【Operating Instructions】

The low‑temperature cold resistance tester is specially designed to test the requirements under various low‑temperature environments for materials such as shoe upper leather, finished shoes, rubber, shoe soles, synthetic leather, and plastic finished shoes, in order to understand the adaptability of various materials or finished shoes to cold climates or cold terrain areas. The instrument is made entirely of stainless steel (SUS) and can be equipped with various test fixture devices to meet the requirements of different test standards.
