Product Overview
Automatic cleanroom class evaluation with 95% UCL confidence per Fed Std 209E. Built-in printer delivers timestamped reports on site — perfect for surprise audits and third-party certification visits.
The GCC-CSJ-DⅡ is a portable, six-channel laser airborne particle counter designed for cleanroom classification, routine environmental monitoring, and filter integrity testing. With a detection sensitivity of 0.3 μm and simultaneous measurement across six particle size channels, it provides comprehensive contamination data for ISO Class 5 through Class 8 cleanrooms.
