1. PRODUCT OVERVIEW
The PM-350 is a professional-grade digital aerosol photometer designed for the critical task of HEPA/ULPA filter integrity testing. Utilizing advanced laser scattering technology, it provides high-speed detection of aerosol concentrations for downstream leak scanning and upstream concentration verification. The system features a high-performance internal pump and a unique dual-display architecture—the main unit and a smart scanning probe—allowing technicians to monitor results in real-time while focusing on the filter surface.
2. KEY FEATURES
-
Precision Flow Control: Powerful internal pump maintains a steady, regulated sampling flow rate for consistent filter scanning.
-
Smart Dual Displays: Features a primary 5-inch color touch screen on the main unit and an integrated 3.5-inch color touch screen on the Smart Probe for seamless field operation.
-
Wide Dynamic Range: Measures aerosol concentrations from 0.0001% to 100.0% with high precision.
-
Multi-Aerosol Support: Digital calibration for common challenge aerosols including PAO, DOP, and Corn Oil.
-
Audit-Ready Reporting: Internal memory for 20,000 sample records, with USB data export for GXP-compliant documentation.
-
Auto-Zero & Rapid Response: Instantaneous baseline stabilization and high-frequency sampling for efficient leak detection.
