High-Precision Detection

Measure the smallest particles

The Particle Check range detects particles as small as 0.1 μm, making it suitable for ISO 8573-1 Class 1 air quality monitoring and helping ensure top-level air purity.

Fast & accurate analysis

Higher flow rate, better results

With a flow rate of 28.3 l/min (10x higher than standard particle counters), the Particle Check range captures more particles in less time, ensuring faster, more reliable results.

Flexible Monitoring

Stationary or mobile use

Choose between continuous air quality monitoring with the stationary S1/S2 models or spot-checks using the portable M1/M2 service case, adapting to your operational needs.

  • Highly precise, optical laser particle counter for use in compressed air and technical gases
  • Highly precise optics for detecting the smallest particles up to 0.1 μm and therefore suitable for monitoring the compressed air class 1 according to ISO 8573-1 
  • The flow rate of 28.3 l/min (1 cfm) is 10 times higher than that of the particle counters generally available on the market (usually 2.83 l/min). Advantage: Counts the smallest particles with high counting accuracy at the same time 
  • Due to the digital data transfer (Modbus-RTU) to the chart recorders Check Box S4 or Check Box S6, 3 measuring channels can be transferred at the same time (without any faults due to check sum) 
  • The class 1 filter which is included in the scope of delivery can be used for on-site calibration at any time. Contaminations on the optics can therefore be quickly detected or eliminated.
