TSI AeroTrak® Portable Particle Counter Model 9110 sets a new standard with its precise measurement capability, reaching particles as small as 0.100 μm. This achievement is made possible by employing a patented HeNe laser technology, which not only requires low maintenance but also boasts an enhanced signal-to-noise ratio for reliable results. Designed to excel in cleanroom environments, the Model 9110 is particularly suitable for performing ISO-14644-1 classifications for Class 1 and Class 2 cleanrooms. Its applications span across cleanroom monitoring, process tool monitoring, and filter test tasks.

The Model 9110 goes beyond accuracy by providing pass/fail reports for ISO 14644-1 through its onboard printer and the supplied TrakPro™ Lite Secure download software. The device facilitates easy management by allowing multiple particle counter configurations to be stored and uploaded as needed. It can be used both as a standalone particle counter or integrated seamlessly into a facility monitoring system, such as TSI’s FMS 5.

Ensuring adherence to strict quality standards, the Model 9110 complies with all requirements specified in ISO 21501-4. Its calibration is performed with NIST traceable PSL spheres, using TSI’s world-class Classifier and Condensation Particle Counters, ensuring accurate and dependable measurements.
