LiQuilaz® II Liquid Particle Counter E Series

Sensitivity range: 1.5 – 125 µm

Models: E15P, E20, E20P

The LiQuilaz E15, E20, and E20P optical particle counters are volumetric particle counters with sizing sensitivities from 1.5 – 125 μm.

Volumetric particle counters offer the highest precision possible by measuring 100% sample volumes so that short sampling intervals can be utilized without sacrificing statistical significance.
