Low Volume Air Samplers PM10 & PM2.5

The Tisch Environmental TE-Wilbur is the most advanced low volume air sampler system in the industry. You can configure the TE-Wilbur low volume air sampler for TSP, PM10, PM2.5, PM1, as well as any other particulate separation device with a flow rate between 1-25 SLPM. Featuring modern, industrially hardened components paired with innovative design and state-of-the-art manufacturing practices, the TE-Wilbur is the future of particulate collection.

The TE-Wilbur is ideal for Environmental Monitoring, Fence Line Monitoring, and Industrial Monitoring and is designed to operate in any environment with quick and easy deployment. The TE-Wilbur exceeds all performance specifications set forth by the USEPA for low-volume particulate collection.

An Intuitive Low Volume Air Sampler

Our low volume air sampler’s user interface is a full-color 5.7″ touchscreen that utilizes intuitive control. The touchscreen was developed specifically to satisfy the recommendations of instrumentation operators. The TE-Wilbur low volume air samplers feature easy-to-access menus, step-by-step calibration, and on-screen status alerts for efficient operation wherever you may be.

The intuitive TE-Wilbur control is provided by our industrialized programmable logic controller (PLC), whose programming is USB downloadable and MODBUS compatible. Volumetric flow is controlled through an integrated mass flow meter and onboard ambient temperature and pressure sensors. Filter set-up and exchange are achieved through the Tisch-designed filter exchange mechanism, which allows easy one-handed operation. In addition, the filter exchange mechanism does not require continual adjustment to seal your filter against leaks. Data can be retrieved through any MODBUS compatible data acquisition system or can be easily downloaded and transported with your filter on a USB drive.

The Benefits of Our PM10 & PM2.5 Low Volume Air Samplers

When you choose a TE-Wilbur low volume air sampler, you can expect to benefit from a wide range of features for your air quality monitoring procedure. One of the most significant benefits is the intuitive user interface, which significantly cuts down on setup time. Additionally, the brushless motor technology employed in our samplers reduces the need for maintenance, ensuring long-term reliability.

Our samplers also come with an easy-to-follow step-by-step calibration process, which simplifies the calibration procedure and reduces the likelihood of errors. The programmable timer feature enables flexible sampling schedules, allowing users to set up customized sampling schedules to meet their specific needs.

Finally, our zero-adjust filter exchange mechanism allows for quick and easy filter changes, minimizing downtime and making routine maintenance more straightforward. With these features and benefits, our low volume air samplers are the ideal choice for anyone looking to monitor air quality with ease and accuracy.
