Low-Temperature Tensile-Retraction Testing Machine
Y-8791TR
Low-Temperature Tensile-Retraction Testing Machine utilizes compressor mechanical cooling to maintain a constant low-temperature environment and can heat up at a set rate, with alcohol as the cooling medium. It employs a dedicated tensile fixture and displacement sensor to measure the temperature at which the deformation of materials like rubber reaches a specified value as the temperature gradually increases after a period of freezing. The machine is equipped with an integrated color LCD touchscreen control system, one-click testing software, and can automatically calculate relevant parameters.
