Portable Air Particle Counter Model 3411
MET ONE 3411 portable air particle counters are designed specifically for semiconductor cleanroom monitoring, process benchmarking and particle troubleshooting applications. With industry leading ISO 21501 accuracy and reproducibility, the MET ONE 3411 is the cleanest 0.1um portable air particle counter in the market.
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
