SED-500HWX-S High-Temperature Constant Temperature Test Chamber. Internal volume 480-500 L (inner chamber 800x700x900 mm W x D x H), weight ~100 kg. Temperature range RT+10 to 300 deg C, fluctuation +/-0.5 deg C (RT-100
مبدأ العمل
Sample is placed inside a SUS304-lined chamber. PID controller(RKC PXR-9) regulates a nichrome heating element via solid-state relay; a blower(90 W standard / 400 W optional) creates forced-air circulation around the inner duct. A damper manually switches between recirculation and air exchange modes. Cooling is by fan-forced ventilation. Multi-layer overheat protection: power leakage breaker, thermal fuse, fan thermal switch, upper/lower temperature alarms, and over-temperature shutdown.
