Description
The Kanomax 3910 & 3905 Portable Particle Counters combine precision, portability, and compliance in a single device, making them the ideal solution for cleanroom certification and critical environment monitoring. With advanced features, robust construction, and user-friendly operation, they ensure reliable performance in the most demanding applications.
Featherlight, Compact & High-Precision Airborne Particle Counting
The Kanomax Model 3910 & 3905 Portable Particle Counters are among the smallest and lightest 6-channel instruments available in the industry, designed to deliver high-precision airborne particle measurements in critical environments.
With a sensitivity down to 0.3 microns and flow rates of 50 LPM (Model 3910) and 28.3 LPM / 1 CFM (Model 3905), these advanced devices provide fast, accurate, and reliable results for cleanroom certification and environmental monitoring.
Equipped with a large color touchscreen and an intuitive, user-friendly interface, the instruments simplify measurement procedures through pre-programmed standards, guiding users step-by-step through certification processes.
An optional Climomaster™ environmental probe further enhances functionality by enabling simultaneous measurement of air velocity, temperature, and humidity—making these devices a complete solution for cleanroom validation.
