The DS500 PM10 sampler is programmed to run for exactly 7 days, after which it automatically turns off. The sampler can also be turned off mid-run and the onboard data logger automatically records the run start and end date, and times. The sampler also automatically deactivates if its battery drops below a certain voltage and if the pump reaches its maximum demand due to exceptional dust concentrations etc.

 
Each DS500 is supplied with 2 PM10 samplers to allow for continuous monitoring. Used samplers must be returned to DustScan offices for data removal, servicing and filter exchange.

Samplers are fitted with 37mm glass micro-fibre filter papers. Other filter papers such as quartz filters can be supplied on request. All filters are pre and post conditioned in accordance with BS EN 12341 guidelines in the DustScan laboratory. Filters are pre and post weighed using a 5 decimal place balance. DustScan laboratory procedures follow BS EN 45001 guidelines.

 

Filter weights and sampler run data are entered into the DustScan database for tabulation and reporting. The μg/m3/24hr average PM10 concentration is calculated from the 7 day sample.

 

The directional sticky pad sampling component of the DS500 is based on our DS100 gauge and should be collected over the period of 1 week. Where dust levels are anticipated to be very low, samples may be collected over a maximum of 2 weeks. Frequent and regular sampling ensures a meaningful dataset is obtained.
