    Abstract

    In this work, a device for aerosol charge measurement and dust sampling is presented. The device is basically an open-ended Faraday pail with a filter to collect the sample. It can be attached to a pneumatic transfer line or it can be used with hose, depending on the situation. When the system was developed, special emphasis was put on the ease of use and reliability. The device can be assembled and disassembled with one twist. The reliability and the operation of the device was tested using two different powder materials, test dust and polystyrene pellets, and four different hose materials. By combining these materials, different extents and polarities of tribo-charge were obtained. The device proved to be easily operated and the test results showed good reproducibility.
