Dry Foam Frisbee-type Dust Deposit Gauges (additional Directional Sticky Pad adaptor available on request)
This instrument is designed to measure dust deposition, usually quoted as mg/sq m/day
The collector is an anodised aluminium device looking like an inverted Frisbee. It has an operational diameter of 227mm so its area is 0.04 m2.
If the gauge collects W mg in D days, then the deposition rate is given by:
Deposition = [24.7*W]/D mg/m2/day
For example, if 175mg were collected in 30 days, the result would be:
Deposition = [24.7*175]/30 = 144.1 mg/m2/day
