UL746A Glow-wire Test ApparatusModel: ZRS-3H
The ZRS-3H Glow-wire Test Apparatus is according to IEC60695-2-1, IEC60695-2-10, IEC60695-2-11, IEC60695-2-12, IEC60695-2-13 (GB/T5169.10, GBT5169.11, GBT5169.12, GB/T5169.13) < basic testing methods of Glow wire, basic testing methods of Glow wire device>, UL 746A, IEC829, DIN695 and VDE0471. The Glow wire tester ZRS-3H/ZRS-3HS is suitable for resistance to abnormal heat and fire test on lighting lamps, electronic products and household appliances. It uses high-temperature coating spraying on steel structure and imported instrument display, with easy operation and stable performance. The equipment is applicable to flame resistance test of all levels of QC departments and corresponding enterprises.
