The TE-5170DX is a high volume air sampler designed for Total Suspended Particulate (TSP) sampling in compliance with EPA reference method requirements as specified in 40 CFR Part 50, Appendix B. This configuration delivers reliable particulate collection with no size-selective inlet, making it suitable for ambient air monitoring, research applications, and lead monitoring programs.

Technical Operation

The TE-5170DX employs Mass Flow Control (MFC) technology to maintain consistent sampling conditions. The hot wire anemometer probe monitors flow in real-time and automatically adjusts motor speed as the filter loads with particulate, ensuring stable flow rates throughout the sampling period. Flow measurements are corrected to EPA standard conditions (25°C, 760 mm Hg) for accurate concentration calculations.

Key Specifications

Flow rate range: 39-60 ft³/min (1.1-1.7 m³/min)
Power: 220V, 50Hz configuration
Motor: Brush-style motor with proven field reliability
Timer: Digital timer with programmable sampling periods
Particle collection: Up to 25-50 µm aerodynamic diameter particles
Filter size: 8" × 10" glass fiber filters

Digital Timer Advantage

The digital timer system provides precise programming control and eliminates the mechanical wear issues associated with traditional mechanical timers. Digital timing is EPA-recommended for ensuring accurate sampling results, with clear display readouts and reliable start/stop functionality for standardized 24-hour sampling periods.

Compatibility and Maintenance

The TE-5170DX uses standard 8" × 10" glass fiber filters meeting EPA specifications for TSP collection. The brush motor design provides cost-effective operation with readily available replacement brushes. Regular maintenance includes brush inspection and replacement as needed based on operating hours tracked by the elapsed time indicator.

Applications

This sampler configuration is ideal for:

Compliance monitoring for National Ambient Air Quality Standards (NAAQS)
Lead monitoring programs as specified in 40 CFR Part 50, Appendix B
Source assessment and environmental impact studies
Research applications requiring total particulate collection
International monitoring programs requiring 50Hz power compatibility

The anodized aluminum shelter construction provides weather resistance for continuous outdoor operation, while the 220V 50Hz power specification makes this unit suitable for international deployments and regions with 50Hz electrical systems.
