HF-8812  換氣式空氣熱老化試驗機
CONVEION AND VENTILATION AGING OVEN
UL1581，VDE，CCC 

本機在試驗電線電纜緣體或被覆之橡塑膠試片，以比較試片老化前與老化后之拉強度及伸長率，本機以熱風循環方式，促使試片老化，內箱密閉性佳，具有抽換內箱空氣裝置，設有溫自動切斷保護。
另附有瓦時計及計時器，具有換氣量測定功能。
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 proteion if over-heated。Inner air is changeable。Also can be used as a drying oven by introducing web-frame。
