Échantilonneur d'air à bas débit modèle MicroVol 1100
 


Description
The MicroVol 1100 low volume air sampler provides a flexible sampling platform for PM10, PM2.5 or TSP particulates and basic meteorological parameters.
The MicroVol 1100 is suitable for both indoor and outdoor applications. The unit is microprocessor controlled and uses a mass flow sensor in conjunction with ambient temperature and pressure sensors to automatically maintain a constant volumetric flow rate.
Particulates are size selected and collected on a sample filter for gravimetric analysis.

Standards

• PM10: AS/NZS 3580.9.9 2006
• PM2.5: AS/NZS 3580.9.10 2006
• CE and C-tick approval
• Manufactured under ISO9001 and ISO14001

Indoor sampling

• Low power consumption
• Quiet operation-ideal for indoor air quality studies
• Volumetric flow control automatically corrected to standard reference temperature
• Ultra-efficient, long life DC pump delivers flow rates of 1.0 to 4.5 l/min

Outdoor sampling

• Wind direction and speed used to activate/de-activate sampler
• Fence line monitoring available with a network of samplers
• Built for all conditions - light weight, rugged weatherproof construction
• Can operate via battery or solar power sources (optional)

Enhanced communication

• RS232 output for data collection and networking
• Filter block and instrument error alarms available to email & sms
• Total control of instrument remotely from PC
• Simple programming of sampling periods, including daily and weekly programs, with in built ‘1-in-X day’
sampling capability
