Glow Wire Test Apparatus Included “inner, Build-in” Fume Hood
Product overview:
This device is manufactured according to the standard of IEC60695-2-10, IEC 60695-2-11, IEC 60695-2-12, IEC60695-2-13, UL746A, IEC 60335, IEC 60598, etc. It also conforms to the standard requirement of UL746A. This device simulates the thermal stress test of glowing component or heat source like overload resistance or ignition source which is caused in s short time. It is suitable for electric and electronic products, household appliances and other material to do fire hazard testing. It is also used in the No flame ignition source fire test to test initiation temperature and flammability index of related glowing filament.
This instrument adopts a new design concept and uses an advanced digital stepping motor to achieve precise positioning, and at the same time, realize rapid adjustment after specimen replacement, which truly meets the requirements of simple and convenient operation. The control system adopts PLC+HMI+stepping motor control, each parameter can reflect the real situation of relevant parameters, which is more real-time and accurately, and the operation is intuitive and convenient, meeting the needs of scientific research, far exceeding similar products.
