HF-8812  换气式空气热老化试验机
CONVECTION AND VENTILATION AGING OVEN
UL1581，VDE，CCC 

本机在试验电线电缆绝缘体或被覆之橡塑胶试片，以比较试片老化前与老化后之抗拉强度及伸长率，本机以热风循环方式，促使试片老化，内箱密闭性佳，具有抽换内箱空气装置，设有超温自动切断保护。
另附有瓦特小时计及计时器，具有换气量测定功能。
This tester is designed to test rubber & plastic specimens of cord's insulator or jacket。The tensile strength，elongation and hardness of dumbbell specimens before / after aging can be compared。This tester uses hot-air-circulation to make specimens aging。Its interior is sealed well and it is equipped with the induced draft device & auto shut-off protection if over-heated。Inner air is changeable。Also can be used as a drying oven by introducing web-frame。
