Operator Uses Mini-Master® Flowmeter to Verify Air Flow into Portable Dust Monitor

The small size, accuracy, and low cost of the Series MM Mini-Master® Series flowmeter lends itself perfectly to use in this portable, battery-operated dust monitor. Using a light scattering electronic sampler, a small vacuum pump draws air through the flowmeter into the sampling chamber, and the flowmeter verifies the proper volume of sample air flow. Readout is digital and directly in dust weight per cubic meter of air.
