Which is a good Sichuan safety helmet impact puncture tester

Fire helmet impact puncture resistance testerIn the puncture resistance test of fire helmets, a 3kg puncture cone is used to freely fall from a height of 1m and impact the helmet. After contact with the puncture,

The contact indicator emits an alarm signal to determine if the fire helmet has penetrated. Can be used by inspection departments and research institutions.

Applicable standard GA44-2015 Fire Helmet Test Method GB811-2010 "Motorcycle Member Helmet"

1. The instrument realizes microcomputer fully automatic control

2. Free replacement of drop hammer and puncture hammer, simple operation

3. Professional high-precision dynamic force sensor

4. Touchscreen digital display, accurate to 1N, automatically savedexperimentforce value

5. Easy to adjust and control the impact height; Measuring 1m height is simple and intuitive

1. Head mold: comply with the provisions of Appendix A of GB/T 2812-2006.

2. Test stand: capable of controlling the lifting, suspension, and release of impact hammers and puncture cones.

3. Falling hammer: with a mass of 5-5.01kg, the hammer head is hemispherical with a radius of 48mm, made of 45 # steel, and has a symmetrical and uniform shape.

Fire helmet impact puncture resistance tester

The helmet impact puncture tester is specifically designed to test the impact absorption and puncture performance of firefighting helmets. In the impact absorption performance test of fire helmets, the force sensor is rigidly installed between the head mold and the base. After pre-processing, the fire helmet is worn on the head mold, and then a 5kg hammer is freely dropped from a height of 1m to impact the fire helmet. The force value at the moment of impact is measured by a high-sensitivity force sensing device to determine the impact absorption performance of the fire helmet. In the puncture resistance test of fire helmets, a 3kg puncture cone is freely dropped from a height of 1m to impact the helmet. After contact with the puncture, the contact indicator emits an alarm to determine whether the helmet has penetrated. Can be used by inspection departments and research institutions.
