The TE-5170DVXZ is a high volume air sampler configured for 40 CFR Part 50, Appendix B compliant Total Suspended Particulate (TSP) sampling. 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.

Volumetric Flow Control System

Features volumetric flow control (VFC) that maintains constant air flow during the sampling period using differential pressure measurement. This control method automatically adjusts motor speed to maintain consistent volumetric flow rates across varying field conditions, ensuring accurate sample volume measurement regardless of filter loading or ambient temperature changes.

Digital Timer & Control Package

Equipped with a digital timer for precise programming of sampling periods. The sample period must be 1,440 ±60 min. for a valid sample according to EPA requirements. The digital interface provides straightforward operation with clear displays and reliable timing functions for routine 24-hour sampling cycles.

Motor Configuration

Utilizes a proven brush-style motor assembly that delivers the high airflow rates required for TSP collection. The high-volume samples 40-60 cubic feet per minute (ft³/min) of air, providing sufficient sample mass for gravimetric analysis and subsequent chemical characterization of collected particulates.

Sampler Configuration Options

This model is part of Tisch Environmental's TE-5170 series, which offers multiple configurations combining different timer types (mechanical/digital), motor styles (brush/brushless), power requirements (110V/220V at 50Hz/60Hz), and flow controllers (MFC/VFC/VFC PLUS). The DVXZ designation specifically indicates: D=Digital timer, V=VFC controller, XZ=220V 60Hz power with brush motor.

Applications

Designed for ambient air quality monitoring networks, research applications, and compliance monitoring where the measurement process is nondestructive, and the size of the sample collected is usually adequate for subsequent chemical analysis. Particularly suitable for sites requiring TSP monitoring for lead analysis, source apportionment studies, and environmental impact assessments.

The anodized aluminum shelter construction provides weather-resistant protection for all control components, making this sampler suitable for long-term outdoor deployment in ambient monitoring networks.
