Particle Counter Calibration Services

Handheld particle counters can be single or multi-channel, from 0.3 to 5 micron particle sizes.  Applications include clean rooms, laboratories, filter efficiency, respiratory deposition studies, and indoor air quality evaluations. They can give you a firsthand look at particle size distribution that is very useful when designing engineering controls.  Today’s laser technology allows for more portable, lighter meters with touch screen, self-verification, data logging, and reporting.  Particle counter calibration services are important in meeting current standards for better accuracy and verification of count data.  Calibration at CIH Equipment Company verifies count data using NIST traceable PSL spheres and comparison optical and condensation particle counter standards. 

Why calibrate your particle counter?

  • Comparison to NIST traceable monodisperse particles of a specified size, standard deviation, and coefficient of variation.
  • For portable units, we use the ASTM F 328-98 optical comparison method.
  • The reproducibility of our measurements is achieved through proper design and verified through appropriate count calibration procedures and standard reference counters.

Particle counters

Airborne Particle Counters set the industry standard when it comes to detecting airborne pathogens. A particle counter is an instrument that detects and counts physical particles.. Applications for airborne particle counters have a wide range of applications in the medical, pharmaceutical, electronics and aerospace industries to name a few.

Particle counter calibration

Our procedures are designed to maximize the repeatability, reproducibility and accuracy of our instruments. These procedures have been developed in accordance with key standards for particle counters. The reproducibility of our measurements is achieved through proper design and verified through state of the art optical alignment methods, standard reference counters and appropriate count calibration procedures.
