Particle Counters Air and Gas






Our remote and portable particle counters for air and gas are specifically designed for cleanroom environments. Always manufactured to exceed or meet industry standards and requirements, Particle Measuring Systems’ technology provides comprehensive data and accurate results for all users.

For over 45 years, Particle Measuring Systems (PMS) has been the trusted name for particle counting solutions. We distribute a full catalogue of gas and air particle counters for cleanroom environments, as well as provide expert advisory and support services, global customer training, and reliable service and calibration solutions. 

Particle counters are crucial for the manufacturing of critical products within cleanrooms. Our team develops technology that counts particles in a clean environment and then calculates, manages and reports the results. By doing so, we help you improve yield and meet all global regulatory requirements, including EU Annex 1, ISO 14644-1:2015, ISO 8573 and 21CFR Part 11.

Gas and Air Particle Counter Benefits 

Our powerful and effective air particle counter technology services many industries.

Semiconductor and Microelectronics

We help you improve your yield by providing high sensitivity solutions including the Lasair III 110 and the Nano-ID NPC10, monitoring accurately down to 10 nm. We also have remote solutions including the Airnet II, which can be used for continuous cleanroom monitoring. Our high-pressure gas particle counters allow monitoring of gas contamination at line pressures.

Pharmaceutical and Life Science

Meet all regulatory requirements with our instruments. Complete clean room monitoring solutions, including data management, security, and analysis. Choose from remote or mobile cleanroom monitors. We also have adapters for compressed gas monitoring. 

Photonics and Optics

With our specialized experience in photonics and optics, we can help you protect your product with effective air particle counting. The Lasair III can be used for mobile or remote applications.
