Used EXTECH VPC300 #293657922 for sale

EXTECH VPC300 is a powerful particle counter for monitoring and measuring particles in the air. It pays special attention to indoor air quality, measuring particles of 0.3 to 10 microns in size and providing a total particle count (TPC). This counter is ideal for applications such as the identification of sources of indoor air pollution, monitoring of ventilation systems for efficiency and cleanliness, proof of filter performance, and general particle counting. This counter provides digital and analog readings, along with cumulative readings to show the count above a preset size. It is equipped with a built-in, large-capacity battery, a backlight LCD display, and convenient data storage. VPC300 also includes a graphical history capability to review past readings, an audible alarm that can be set to desired levels, and a convenient user interface for easy setup and operation. The particle counter is a multiple-range particle counter for low, medium, and high concentrations. Sample air is pulled into the optical chamber by a two-stage turbine drive system and particles detected in the chamber are classified based on size before being counted. The particles are filtered to specific size ranges, and the size-classified particles are counted and separated into distinct size ranges. This results in an individual concentration of interference-free particles and the total concentration. EXTECH VPC300 offers a robust stainless steel design that has proven to be durable with applications in areas ranging from cleanrooms and laboratories to industrial and HVAC applications. The design also includes an easily-distinguishable, friendly graphical display with adjustable parameters. Furthermore, this particle counter has an intuitive user interface with convenient storage capabilities for both readings and alarm settings. VPC300 is a reliable and versatile particle counter to meet the requirements of any environment. In delivering accurate airflow and particle readings, the EX TECH EXTECH VPC300 displays clear, well-defined data, improved by additional graphical display options. This device is a highly recommended product for any monitoring and measuring needs.
