CSJ-DⅡ Laser Airborne Particle Counter
Portable six-channel laser particle counter for cleanroom classification, GMP environmental monitoring, and ISO 14644 compliance verification.
Product Overview
The CSJ-DⅡ is a compact, portable laser airborne particle counter engineered for cleanroom classification, environmental monitoring, and airborne particulate contamination detection in pharmaceutical manufacturing, electronics, food & beverage, aerospace, and research laboratory environments.
Manufactured by Suzhou Hangdi Environmental Technology Co., Ltd. (formerly Suzhou Automation Instrumentation Research Institute), the CSJ-DⅡ delivers simultaneous six-channel particle sizing at 0.3, 0.5, 1, 3, 5, and 10 μm — with particle sensitivity maintained at the 0.3 μm level, ensuring accuracy at the ISO Class 5 (Class 100) threshold and above.
Why It Matters: With automatic cleanliness class evaluation based on the US Federal Standard 209E at 95% UCL confidence level, built-in real-time clock and printing functionality, and metric/imperial unit conversion, the CSJ-DⅡ streamlines cleanroom compliance verification. It automatically grades cleanrooms across five cleanliness classes (ISO Class 5 / Class 100 through ISO Class 8 / Class 300,000), with configurable threshold alarms — making it an essential tool for GMP audits, cleanroom commissioning, and routine environmental monitoring.
