DRK312B Friction charge tester for type I fabric (Faraday tube)
Short Description:
Introduction At 20±2)℃; Relative humidity: 30% ± 3% under atmospheric conditions, test samples are rubbed with specified friction materials to make them charged and then put into Faraday cylinder to measure the charge of the samples. And then convert that to charge per unit area. The measuring instrument consists of friction device and charge measuring instrument. Friction device consists of roller rubbing machine or friction rod, pad, cushion and insulating rod. Charge measuring instrument...
Introduction
At 
20±2)℃; Relative humidity: 30% ± 3% under atmospheric conditions, test samples are rubbed with specified friction materials to make them charged and then put into Faraday cylinder to measure the charge of the samples. And then convert that to charge per unit area. The measuring instrument consists of friction device and charge measuring instrument. Friction device consists of roller rubbing machine or friction rod, pad, cushion and insulating rod. Charge measuring instrument: Faraday tube, capacitor, charge meter.
