Particle Counter Calibration
Airborne particle counting is essential for maintaining cleanroom environments where tiny particles can compromise product quality, application processes, and even end-user safety.
Particle counter calibrations is vital to ensuring your units are performing as they should be, providing you with confidence on the monitoring data you rely on every day.
Whether you’re operating in a GMP pharmaceutical cleanroom, or an ISO-certified plastics manufacturing facility, particle counters give you reliable and accurate measurements following annual calibration.
An overview of particle counters
Used for day-to-day routine monitoring, during contamination incidents, and as part of cleanroom validation, particle counters play a critical role in safeguarding sensitive applications, identifying process weaknesses, and evidencing compliance with ISO 14644 and GMP standards.
Particle counters typically use light scattering to quantify the total number of particles within a defined size range in a given sample volume. However, the internal optics, lasers, and flow rates naturally degrade, causing readings to drift and inaccurate results. This is where particle counter calibration restores the accuracy and reliability your applications need.
The importance of annual particle counter calibration
Routine and continuous monitoring of a cleanroom’s environment requires monitoring systems including particle counters.
As the only guaranteed method of recording and evidencing accurate air cleanliness levels, particle counters display readings in two columns; differential (the number of particles within a specific, defined size range) and cumulative (the number of particles from a minimum size, upwards).
Due to various factors, including desensitisation of lasers, blockages, and natural degradation, particle counters can function inefficiently, resulting in false, inaccurate readings of airborne particles at both in-operation and at-rest conditions.
Regular particle counter calibration verifies and resets the units against known, traceable standards so it can accurately count particles without falsely inflating data.

Particles Plus particle counter UK calibrations lab
Connect 2 Cleanrooms has the only UK calibrations laboratory with the authority to calibrate Particles Plus particle counters, removing the need to ship units overseas, providing you with a fast turnaround, and reducing the risk of damage in transit.
All units are calibrated to ISO 21501 standards, and calibrations are performed to exacting tolerances using N.I.S.T traceable equipment and particle media.
Frequently asked questions
We offer calibration of Airy, Aerotrak, EMS, Kimo, Met One, and Particles Plus particle counters, with calibrations performed in ISO 17025 conditions.
ISO 21501-4:2018 states, “The calibration of the LSAPC should be conducted at an interval equal to or shorter than one year. The requirements should be met during the calibration interval.” The calibration certificate we provide covers your unit for 12 months.
This is dependent on your model, number of units, and condition of your particle counter. However, we offer an average turnaround of 7 – 10 working days and even an express, same-day service on select particle counters units. For more information and an accurate quote, speak to a member of our team.
ISO 21501-4:2018 is an international standard that specifies the calibration and verification methods for light scattering airborne particle counters, ensuring the units are providing accurate, repeatable, and traceable data.
No! We have a team of trained, licensed experts who perform particle counter calibrations at our head office in Halton. This gives you a faster turnaround and reduces the risk of unit loss or damage during transport.
