Fingerprint Powder Brush
The fingerprint powder brush is the basic used method in the field. Because the powder particle is very small, and it is easy to form dust in the process of fingerprint scanning as well as being harmful to the health of the investigation technician. If the powder is too much, it is easy to paste the fingerprint. If the powder is too little, it is difficult to show the fingerprint clearly. However, this model fingerprint spraying brush is used to control the powder on the brush to prevent the dust from being appeared, and not be affected by the powder amount. It is a good product for the basic handling personnel.
