LSA Flow-Set High Volume Sampler (HiVol)

Measure

PM2.5, PM10 or TSP

Description 

The LSA Flow-Set High Volume Sampler was designed out of necessity, it combines ease of use and accuracy of sampling to create an effective and efficient HiVol. Uniquely, the LSA Flow-Set HiVol is fitted with a variable speed pump controlled by true mass-flow sensing removing the need for temperature and and pressure corrections. 

Features

• Constant air flow - maintained well within 1% of the preset flow rate in normal operating conditions.
• True mass-flow sensor - no need for temperature and pressure corrections.
• Low energy consumption - because motor load is determined by the filter load and not by mechanical restrictions.
• Low wear and long life because of low load - the vacuum pump has been proven in power stations at full load around the clock for many years. 
• The absence of other mechanical or moving parts eliminates problems found in some products.
• Low noise, quiet running - does not attract attention or annoy neighbours.
• Soft start drives - ensuring the start current demand is kept at a very low level.
• User-friendly filter collection and replacement.
• Secure casing - preventing dust and rain ingress while permitting easy access for service.
• The flow set incorporates well-proven PM10 and PM2.5 Heads allowing it to sample a variety of particle sizes.
