Abstract :
The aim of this project is the construct of portable dust monitoring unit from any area with the diaphragms pump. Dust passes in the impactor and kept by high voltage. Quartz crystals which keep dust occurre difference output frequency and show it on the LCD display. The measurement time was approximately 30-60 minute. Instrument size is 20times30times8 cm and dust size is no bigger than 10 micron.
