TSP Hi-Vol Air Sampler - MFC, Mechanical Timer, Brush Motor, 110V SKU: TE-5170

High Volume Air Sampler for Total Suspended Particulate (TSP) Collection

The TE-5170 delivers reliable TSP sampling for EPA-compliant ambient air quality monitoring in accordance with 40 CFR Part 50, Appendix B. This EPA reference method provides measurement of total suspended particulate matter mass concentration in ambient air for determining compliance with national ambient air quality standards.

Mass Flow Control Technology

The integrated mass flow controller (MFC) maintains precise flow rates between 39-60 ft³/min throughout the 24-hour sampling period. The hot wire anemometer probe continuously monitors flow and automatically adjusts motor speed as the filter loads with particulate matter. This active flow control ensures consistent sampling conditions and accurate volumetric calculations required for TSP concentration determination.

Key Specifications

• Flow Control: Mass Flow Controlled (MFC)
• Motor: Brush-style, proven field-ready design
• Timer: 7-day mechanical timer for simple operation
• Power: 110V, 60Hz
• Sample Period: 1,440 ±60 minutes (24 hours) for valid samples
• Particle Collection: Aerodynamic diameters of approximately 100 µm or less

Complete Shelter System

Housed in an anodized aluminum outdoor shelter with gabled roof design that protects equipment while allowing unrestricted airflow from all four sides. The weatherproof construction minimizes maintenance requirements in field environments. Includes integrated chart recorder for continuous pressure monitoring and elapsed time indicator for tracking sampling periods and motor maintenance intervals.

EPA Compliance Applications

Essential for ambient air monitoring programs requiring TSP data for NAAQS compliance, including lead monitoring where TSP samples are collected using 40 CFR Part 50, Appendix B procedures. Suitable for state and local air quality agencies, industrial source monitoring, and research applications requiring gravimetric particulate determination.

Filter and Analysis Compatibility

Accommodates standard 8 × 10 inch glass fiber filters for gravimetric analysis. Filters are weighed before and after sampling to determine net weight gain, with TSP concentration calculated as mass of collected particles divided by air volume sampled, corrected to EPA standard conditions and expressed in µg/std m³.
