Renting Particle Counter equipment can help to reduce the worry associated with validation, annual calibration and maintenance costs.  Our BT-620 unit is a portable airborne particle counter with a small footprint. This allows you to move the unit around and set it down, rather than holding the unit while sampling. The Particle Counter comes equipped with all of the appropriate accessories. The unit is calibrated annually to ISO 21501-4:2007, which is required for ISO 14644 Cleanroom Classifications. No software is required to export data. Data is available immediately on the backlit LCD display, or available to download directly into excel.
