The TE-5170DVX is a complete high volume air sampler configured for 40 CFR Part 50, Appendix B compliant Total Suspended Particulate (TSP) monitoring. This system collects particles with aerodynamic diameters up to approximately 100 µm for ambient air quality assessment and regulatory compliance monitoring.

Volumetric Flow Control Technology

The VFC (Volumetric Flow Control) system uses differential pressure measurement across the loaded filter to automatically maintain consistent volumetric flow rate throughout the sampling period. This technology compensates for filter loading and environmental conditions, ensuring accurate sample volume determination required for precise concentration calculations.

Key Specifications

Power: 220V, 50Hz international configuration
Digital timer with programmable sampling periods
Brushed motor drive system with proven field reliability
Anodized aluminum weather shelter
Nominal flow rate: 40-60 CFM (1.13-1.70 m³/min)

Digital Timer & Control

The integrated digital timer provides straightforward programming for repeatable 24-hour sampling cycles as specified in the TSP reference method. The sample period must be 1,440 ±60 min. for valid regulatory samples. Digital controls offer improved accuracy and reliability over mechanical timer systems.

Brush Motor System

The brushed motor assembly delivers dependable performance in demanding field environments. Brush-style motors are widely used throughout the ambient monitoring network for their proven reliability and straightforward maintenance requirements. The motor provides sufficient power to maintain target flow rates even with high particulate loading conditions.

Applications

This method provides a measurement of the mass concentration of total suspended particulate matter (TSP) in ambient air for determining compliance with the primary and secondary national ambient air quality standards for areas still monitoring TSP. Applications include:

Regulatory compliance monitoring for TSP NAAQS
Lead-in-TSP monitoring networks
Source impact assessment
Industrial hygiene monitoring
Research and baseline studies

Configuration Notes

The TE-5170DVX represents the digital timer, VFC, brush motor, 220V 50Hz variant in the TE-5170 sampler family. Alternative configurations are available with different timer types (mechanical vs. digital), motor technologies (brush vs. brushless), power requirements (110V 60Hz, 220V 50Hz, 220V 60Hz), and flow control methods (MFC, VFC, VFC PLUS).

TSP sampling follows 40 CFR 50, Appendix B, the EPA reference method for high-volume collection of total suspended particulate matter. The concentration of total suspended particulate matter in the ambient air is computed as the mass of collected particles divided by the volume of air sampled, corrected to standard conditions, and is expressed in micrograms per standard cubic meter (µg/std m³).
