F242 Glow-wire tester, By simulating the thermal stress caused by heat source or ignition source such as hot component or overload resistor in a short period of time, so as to test the flammability and ignitability of circuit component, which is widely used in electronic and electrical, household appliances, household and industrial lighting, electrical insulation materials and so on. And, it can predict the safety during use of circuits, effectively control production and verify product performance.

1.During the use of electrical materials, it may reach excessive temperature and cause fire hazard due to overload, short circuit, poor electrical contact or other fault conditions. The glowing-wire test refers to a simulated an overloaded resistance heat source to apply thermal stress to the sample in a short period of time. The fire risk of the sample is assessed by observing the light-off state of the sample and measuring relevant indicators.

2.After the heating wire of the specified material and shape is heated to the test temperature (550C - 960C) with a large current by the

glow-wire test device, so as to confirm that the temperature does not fluctuate obviously within 60 seconds, and the test piece is burned vertically for 30 s at a specified pressure (1.0 N). Measure the ignition hazard of the finished electrical and electronic equipment according to whether the test materials and the mats are light-off or holding time.lt can measure the light-off property, light-off temperature, flammability and flammability index of solid insulating materials and other solid combustible materials.

Major Features

Transparent safety door

The heat-resistant glass observation window allows the test to be observed at any time during the test while keeping the test free from external environmental disturbances.

Automatic heating, illumination, exhaust device

Glowing-wire automatic heating timing, equipped with automatic control of the glowing-wire contact position, precise control, convenient and reliable, and the test device is equipped with lighting and exhaust.

Intelligent touch screen control panel

The microcomputer control system is more efficient and reliable, and the programmable 7-inch color LCD touch screen realizes various functions such as control, detection, calculation and data display.

Stepping motor control - accurate moving speed

The moving speed of the sample is controlled by high-end stepping, which has high precision and long service life. In addition, the test device is equipped with flame ruler, and the flame height can be observed at any time during the test.

Sample rack dis-assembly type design

The sample holder of the test device can be removed for loading and cleaning,and it use physical pressure, which has precise pressure,convenient operation and high efficiency.
