Product information
Particle counter PC 400 — stationary solution for compressed air and gases. The high-precision optical particle counter PC 400 measures particles from 0.1 μm and is suitable for monitoring compressed air quality class 1 (ISO 8573). It monitors the correct function of installed filter elements and immediately detects any filter breakthrough. Automatic monitoring of the compressed air sampling flow ensures the availability of particle-free compressed air.

Key benefits

• High-precision optical laser particle counter for compressed air and technical gases.
• High-precision optics for detection of the smallest particles down to 0.1 μm (suitable for monitoring compressed air class 1 according to ISO 8573-1).
• Sampling flow 28.3 L/min (1 cfm) — approx. 10× higher than common counters (usually 2.83 L/min), improving counting accuracy for small particles.
• Digital data transmission (Modbus RTU) to DS 400 or DS 500 recorders, allowing simultaneous transmission of 3 measurement channels with checksum error checking.
• Class 1 calibration filter included for on-site calibration to quickly detect or exclude optical contamination.

Stationary solution (examples of included equipment)
