Dust monitoring Bergerhoff Gauges to measure dust deposition

The Bergerhoff Gauge dust monitoring instrument is used on location and designed to measure for dust deposition, usually quoted as mg/m2/day.

The collector is a 1.5 litre PET bottle with a neck diameter of 90 mm, so its area is 0.00636 m2.

If the gauge collect W mg in D days, the the deposition rate is given by:

Dust Deposition = W/0.00636/D or [157.2*W]/D mg/m2/day

For example, if 14mg were collected in 28 days, the result would be:

Deposition: [157.2*14]/28 = 78.6 mg/m2/day
