The Tisch Environmental TE-Wilbur is the most advanced low volume air sampler system in the industry. The TE-Wilbur can be configured 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. The TE-Wilbur is designed to operate in any environment and is set up for quick and easy deployment. The TE-Wilbur exceeds all performance specifications set forth by the USEPA for low-volume particulate collection.
The TE-Wilbur low volume air samplers user interface is a full-color 5.7″ touchscreen which utilizes intuitive control. The touchscreen was developed specifically to satisfy the recommendations of instrumentation operators. The TE-Wilbur features easy to access menus, step by step calibration and on screen status alerts. The 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 on-board ambient temperature and pressure sensors. Filter set-up and exchange is 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.
Benefits
