The AELAB Y09–550 and Y09–5100 Laser Particle Counters offer high-precision monitoring of airborne particles in ISO Class A and B clean environments. Equipped with advanced laser sensors, real-time LCD displays, and high-capacity data logging, these instruments are designed for fast, accurate sampling with software-ready data export for regulatory reporting.
The Y09 – 550 and Y09 – 5100 Laser Particle Counters are precision instruments designed to monitor airborne particle concentration and size within cleanrooms and controlled environments. These devices use a semiconductor laser light source for accurate detection and feature a large touchscreen interface for intuitive operation.
The Y09 – 550 is compact, lightweight, and ideal for routine monitoring in Class A and Class B clean areas, while the Y09 – 5100, with its high flow rate of 100L/min, is particularly suited for applications requiring fast, large-volume air sampling.
Both models include:
Microprocessor control
Data storage and printing capabilities
PC connectivity with downloadable software
Simple operation and minimal maintenance
These particle counters are widely adopted across industries including pharmaceuticals, biotechnology, aerospace, medical devices, cosmetics, optics, and food production, where clean air compliance is critical.
