DRK312B Fabric Friction Charging Tester (Faraday tube)

Under temperature: (20±2)°C; relative humidity: 30%±3%, the sample is rubbed with the specified friction material, and the sample is charged into the Faraday cylinder to measure the charge of the sample. Then convert it to the amount of charge per unit area.

Technical description of the instrument:
Under temperature: (20±2)°C; relative humidity: 30%±3%, the sample is rubbed with the specified friction material, and the sample is charged into the Faraday cylinder to measure the charge of the sample. Then convert it to the amount of charge per unit area. The measuring instrument is composed of a friction device and an electric charge measuring instrument. The friction device is composed of a roller friction machine or a friction rod, a backing plate, a cushion seat and an insulating rod. Charge measuring instrument: It is composed of Faraday tube, capacitor and charge meter.
