KANOMAX 3520 Series Piezobalance Dust Monitor

Product Introduction
The KANOMAX 3520 Series Piezobalance Dust Monitor (Models 3521 / 3522) is an advanced aerosol monitoring instrument that uses PIEZOBALANCE technology to measure the direct mass concentration of particulates. Unlike conventional particle counters, it quantifies particulate mass by detecting frequency shifts in a piezo‑crystal, offering superior accuracy for monitoring oil mist and fine aerosols in industrial and environmental settings.

Key Features

• PIEZOBALANCE Technology — Direct mass concentration measurement, not particle counting.
• Precision Impactors —
  • Model 3521: 4 µm and 10 µm impactors for larger particulates.
  • Model 3522: 2.5 µm impactor for fine aerosols.
• Unique Mass Measurement Method — Particulates are electrically charged and deposited onto a piezo‑crystal; frequency shift correlates to mass.
• Accurate & Reliable — Provides exact particulate mass determination, critical for pharmaceutical, precision engineering, and environmental monitoring.
• Industrial Applications — Automotive manufacturing, metal machining, chemical processing, and workplaces requiring strict air quality control.
• Health & Safety — Helps reduce exposure to harmful aerosols, ensuring compliance and worker protection.
