TSP Hi-Vol Air Sampler w/ MFC, Mechanical Timer, Brush Motor - 110V 50Hz SKU: TE-5170Z

The TE-5170Z is a high volume air sampler configured for Total Suspended Particulate (TSP) collection per EPA reference method 40 CFR Part 50, Appendix B. This system collects particulate matter with aerodynamic diameters of approximately 100 µm or less at flow rates between 40-60 cubic feet per minute during standard 24-hour sampling periods.

Mass Flow Control Technology

The MFC system uses a hot wire anemometer probe inserted into the flow stream to automatically adjust motor speed as the filter begins to collect particulate. This maintains consistent flow rates throughout the sampling period, compensating for filter loading and ensuring compliance with EPA sampling protocols. The mass flow controller responds to changing filter conditions by modulating motor speed to deliver stable volumetric flow.

Key Specifications

• Power: 110V, 50Hz configuration for international applications
• Flow Control: Mass Flow Controlled (MFC) with hot wire anemometer
• Timer: 7-day mechanical timer for reliable start/stop operation
• Motor: Brush-style motor assembly - proven field performance
• Sampling Period: 1,440 ±60 minutes (24 hours nominal)

Applications

Designed for ambient air quality monitoring programs requiring EPA-compliant TSP data collection. This method provides measurement of the mass concentration of total suspended particulate matter in ambient air for determining compliance with national ambient air quality standards. Suitable for regulatory monitoring networks, environmental assessment studies, and research applications where comprehensive particulate characterization is required.

The anodized aluminum shelter features a gabled roof design that allows particulate matter to be drawn onto the filter from all four sides, ensuring representative sampling. The rugged construction withstands outdoor elements with minimal maintenance requirements.

Regulatory Compliance

This sampler meets EPA specifications for TSP reference method sampling. The filter is weighed before and after use to determine net weight gain, with total air volume corrected to EPA standard conditions (25°C, 760 mm Hg), and TSP concentration expressed in micrograms per standard cubic meter. The collected sample size is typically adequate for subsequent chemical analysis of metals and other constituents.
