Met One 3400 Series Portable Air Particle Counters

The MET ONE 3400 portable air particle counter is designed specifically for ISO14644 cleanroom applications. Organize your routine cleanroom monitoring with embedded location and sample recipe management. The MET ONE 3400 portable air particle counter classification wizard assures compliance during periodic cleanroom certification.

The new enhanced MET ONE 3400 Series is the easiest-to-use and easiest-to-integrate portable particle counter for any facility or environmental monitoring programme. It is easy to setup the MET ONE 3400 for routine sampling through the use of software wizards that guide the analyst to configure the instrument for ISO 14644, EU GMP Annex 1 and other common regulatory sampling requirements. Once setup, the instrument is easy-to-use through one-touch sampling and location identification, saving technicians valuable time and reducing potential errors between sampling points.

Once the programming has been established for your first count, it is easy to replicate. Simply copy the complete configuration to a USB stick and transfer the new settings to the next unit. This allows you to quickly and easily create a fleet of particle counters, all alike. And, because all our counters are ISO 21501 compliant, you can be assured that all your instruments will count with the same accuracy and reproducibility.

What's more, with flexible communications options such as Ethernet and 802.11 wireless and an open communications architecture, the MET ONE 3400 may be seamlessly integrated into any facility monitoring or central data management system, so eliminating the need for manual record keeping. The MET ONE 3400 Series is available in 1 CFM, 50 LPM and now 100 LPM flow rates. The new 100 LPM MET ONE 3445 takes just ten minutes to collect 1 m3 samples required to certify Grade A areas per the EU GMP Annex 1 guidance.

The new MET ONE 3400 is faster, easier-to-use and more reliable than ever before.
