Product Description



The TSI AeroTrak® Handheld Particle Counter Model 9303 offers the most features and flexibility for customers interested in a low cost and versatile handheld particle counter. The Model 9303 features a sturdy yet lightweight high-impact injection-molded plastic design for easy handling. The instrument is easy to configure using an intuitive keypad. The internal memory can store up to 1,500 sample records of particle count data which can be conveniently viewed on screen or downloaded using a USB port to TSI's TrakProâ„¢ Lite Secure Software.

The instrument reports up to three particle sizes simultaneously. The middle channel is user selectable for either 0.5, 1.0, 2.0, or 2.5 μm.

The Model 9303 complies with all the stringent requirements set forth in ISO 21501-4. It is calibrated with NIST traceable PSL spheres using TSI's world-class Classifier and Condensation Particle Counters, the recognized standard for particle measurements.
