Glow Wire Test Chamber
Electronic Test Equipment IEC60695-5-10 Glow Wire Testing Equipment
Product introduction of the Glow Wire Test Chamber
The Glow Wire Tester is designed to carry out fire hazard testing on electro technical products in accordance with the provisions of International standards. • The control unit is supplied with all the controls and metering necessary to accurately set the temperature of the glow wire. The wire current is continuously variable by means of the panel-mounted controller and is monitored by the built-in ammeter. • A digital temperature indicator is fitted which, in conjunction with the thermocouple supplied, accurately measures the glow wire temperature. The electrical circuit of the control unit is fully protected by fuses and a miniature circuit breaker and incorporates mains on/off switching and push button control of the output current. Self contained cabinet with large viewing window and dark colored interior.
