Dust deposition
Collects dust that falls onto a collection surface over a sampling period. A Frisbee Dust Gauge provides a sample for dust fall analysis, rather than a continuous electronic reading.

Dust Monitoring:
Equipment, Methods
& Practical Guide
What you collect matters. An introduction to settling dust, directional collection and choosing equipment for your monitoring programme.
Start with the question
What is
dust monitoring?
Dust monitoring gathers information about dust at a location over time.
It can help investigate dust associated with site activity and understand conditions at nearby locations. Construction, industrial operations, remediation and development sites are common settings.
The right approach depends on what you need to learn. Collecting deposited dust is different from measuring airborne particles. Your monitoring programme should define the purpose and method before equipment is selected.
Two different questions
Settling dust.
Airborne particles.
Airborne particulate monitoring
Uses a different type of instrument to assess particles suspended in the air. A deposition gauge is not a substitute for equipment intended to measure airborne particulate concentrations.
Discuss the monitoring objective with a suitably experienced professional before deciding which method you need.
A different perspective
Where is the
dust coming from?
Directional sticky pads collect dust on adhesive surfaces facing different directions. Comparing these samples can help investigate the direction of dust arriving at a location.
Dust flux describes dust passing through an area over time. The collection method and analysis determine how a directional sample is reported; it should not be treated as the same measurement as dust deposition.
Directional Dust GaugeFrom site to sample
A practical monitoring approach.
Plan the monitoring
Agree the purpose, site locations, sampling period and analysis method with the person responsible for your monitoring programme. Deposited dust and airborne particles require different approaches.
Collect a representative sample
Use suitable collection equipment and a consistent procedure. Keep a record of locations, sampling dates, site activity and any events that may affect a sample.
Arrange analysis and review
Discuss sample handling and reporting with your analysis provider before collection. Read the results in the context of the site and the method used.
How often should equipment be checked?
There is no single interval appropriate for every site or programme. Follow the agreed sampling method and equipment guidance, checking the collector, bottles and collection surfaces for damage, interference or contamination. Ask your analysis provider about sample handling before the monitoring period starts.
Questions & answers
Common questions about dust monitoring
Equipment, collection methods and the support available from Fosse Bits.
What is a Frisbee Dust Gauge?
A dust deposition gauge with an open collector for gathering settling dust over a monitoring period. The collected material can then be submitted for dust fall analysis.
What does a Frisbee Dust Gauge measure?
It collects deposited dust. Analysis of the collected sample helps assess dust fall over the sampling period. It does not provide a live reading of airborne particulate concentrations.
How does a Frisbee Dust Gauge work?
Settling dust enters the collector. The collection assembly, bottle and foam trap are used to gather a sample for subsequent analysis. The bird guard helps protect the collector. Ask Fosse Bits about the collection procedure for your equipment.
What is dust deposition monitoring?
Monitoring dust that settles onto a surface over time, rather than measuring particles suspended in the air at a particular moment.
What is directional dust monitoring?
Directional monitoring uses exposed sticky pads to collect dust from different directions. Comparing the samples can help investigate the direction from which dust is arriving.
What is dust flux?
Dust flux describes dust passing through an area over time. Directional sticky pad collection provides samples for dust flux analysis; the results depend on the collection and analysis method used.
What is a sticky pad used for?
A sticky pad provides an adhesive collection surface for directional dust monitoring. Fosse Bits supplies replacement directional sticky pads in rolls of 100.
View sticky padsWhich consumables does the gauge require?
Polyester foam dust traps and, when using the directional adaptor, sticky pads. Collection bottles and replacement components may also be needed as part of your monitoring programme.
Consumables & sparesCan I buy replacement parts separately?
Yes. Fosse Bits supplies consumables, spares and replacement parts. Contact us with the equipment and components you need so we can check your requirements.
Ask about replacement partsDoes Fosse Bits provide dust analysis?
Dust fall analysis and dust flux / sticky pad analysis and reporting are available. Contact us to discuss your samples and the analysis you need.
Analysis & reportingDoes Fosse Bits service environmental instruments?
