Features of MET ONE 3411

Keeps your cleanroom clean

The only 0.1um particle counter without a dirty exhaust fan.

Hot-swappable batteries –100% instrument availability

Hot-swappable batteries eliminate the need to stop measuring while your instrument charges or for powering down, zero counting and powering back up.

Test wizard for easier compliance - organize your cleanroom

Save time and eliminate errors when monitoring your semiconductor production environments.

Sequential sampling - manifold system

Low cost site monitoring solutions can be deployed with the MET ONE Model 3432 manifold. Sample sequentially from up to 32 locations with a single MET ONE Model 3411 series particle counter.

Flexible communications – easy setup and data transfer

Reduce your paperwork with wireless, Ethernet and serial communication options to MET ONE Data Management or your own software solutions.

Intuitive user interface

Easily set up sampling plans by area, location and operating parameter, saving operator time. Eliminate setup errors and save time by exporting setup configuration to USB memory stick and deploy your sampling plan across your entire particle counting fleet!

ISO 21501-4 reliability and accuracy

Designed for exceptional particle counting performance providing ISO 21501-4 compliant unit-to-unit accuracy and reproducibility.
