Digital/Semi Automatic Fine Particulate Sampler
Data Storage is directly on USB
No manual calculation is required for sampling information
Measures both filter as well as ambient temperature
Also monitors operational parameters such as barometric pressure & flow rate digitally.
Automatic control of sample volumetric flow rate and other operational parameters.
Provides data information at the end of each sample period in digital form.
Determines the elapsed sample collection time for each PM2.5
Total Flow has to be recorded manually
Designed according to US EPA 40 CFR 50 Appendix L.
Top plate and wind deflector have been redesigned at a sampling flow rate of 16.67 LPM and unaffected by wind direction and wind speed of ambient air.
Semi Automatic Model stores Data on a Data Logger. The Data logger writes this data on a Pen Drive which can be later transferred to a computer in an Excel Sheet.
The Flow Control is achieved by an Electronic Controller with very precise control over flow rate.
