Handheld particle counters for cleanroom environment monitoring
In cleanroom environments, pinpointing contamination sources and ensuring optimal air quality are critical tasks. Accurate and reliable particle counting is essential for maintaining compliance and safeguarding sensitive manufacturing processes.

Measure airborne particles with precision and ease
The TSI AeroTrak® Handheld Particle Counters are designed for effective spot checking in cleanroom environments. These lightweight, portable instruments allow you to efficiently identify contamination sources, test filter performance, and conduct indoor air quality investigations. Models such as 9306 and 9303 can measure up to six and three channels of simultaneous data, respectively. Both comply with ISO 21501-4 standards, ensuring reliability and accuracy. The 9303 model has a flow rate of 0.1 CFM (2.83 LPM) and monitors particle sizes ranging from 0.3 µm to 5.0 µm. The 9306 model offers user-selectable particle size ranges from 0.3 to 10 µm. These features make TSI AeroTrak handheld particle counters suitable for applications in electronics, industrial, semiconductor, and pharmaceutical industries.
