Glow Wire Test Apparatus is designed to carry out fire hazard testing on electrical product 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.

Feature：
Glow Wire Test Apparatus determine the fire resistance by the fire hazard test, accordance with IEC60695-2-10, IEC60335, IEC60598 and other standards.
The ignition source is imitated by an electrically heated wire loop against which the sample is pressed with a constant force. A miniature jacket thermocouple serves as a sensor for the loop temperature.
The sample has to be fastened to a carriage on which, by means of a tension cord, a weight with a force of 1 N is effective in the direction of the wire loop. Scales enable the reading of the flame height and the depth of penetration. Approx 200 mm below the wire loop a board of pine wood, covered with a layer of tissue paper, is mounted. This device enables to judge the danger of a fire spreading through burning drops or glowing parts falling from the sample. The calibration is done with silver foil, when the foil melts, the measuring unit must indicate a temperature of 960℃
Includes:
white Pine Test Board and five Sheets of Tissue Paper
Glow Wire Loop
Thermocouple Type K
