The LiQuilaz® II E series are volumetric optical particle counters designed to detect particle sizes ranging from 1.5 to 125 µm. These sensors maintain the trusted accuracy, reliability, and repeatability that customers have relied on for years.
The LiQuilaz® II E series features both RS-485 and Ethernet network communications, enhancing their flexibility. The addition of Ethernet also simplifies installation and enhances overall product adaptability.
Volumetric particle counters provide the best precision possible by measuring 100% of sample volumes, allowing for short sampling intervals without sacrificing statistical significance.
