Portable Safety Helmet Anti-Static Resistance Tester In Case Shape

I. Quick Details

II. Description

This tester is used to measure anti-static property of safety helmet.

Test method:

1. The testing room should be in state of constant temperature and humidity.
2. The helmet shall be preprocessed not less than 24h.

Preprocessing method:

Keep the helmet in the environment of temperature 20±2  and humidity 50±5.

stick to two electrodes on the helmet in parallel on the helmet.

3. Length of electrodes: 100mm±1mm; width: 1mm±0.1mm

4. The electrodes are attached by electro-conductive adhesive tape with resistance <1KΩ.

5. Connect megger on the electrodes and read the resistance value.

6. Exchange the electrodes and measure one more time.

7. Record the displaying value. The average value of the two test is the actual surface resistance rate of the helmet.
