Gas airborne particle counter PC 400

nitrogenCO2oxygen

Product information
The highly precise optical particle counter PC 400 measures particles from 0.1 µm and is suitable for monitoring compressed air quality class 1 (ISO 8573-1). It continuously monitors filtration elements installed in the compressed air line and detects filter breaches immediately. The compressed air flow through the particle counter is automatically supervised to ensure representative sampling.
