MET ONE 3425 Portable Wireless
This version of the 3425 includes wireless connectivity, features industry-leading ISO 21501 accuracy and reproducibility and is designed for semiconductor cleanroom monitoring, process benchmarking and particle troubleshooting applications. The 3425 is the cleanest 0.1um portable air particle counter when compared to equivalent models. Unlike many particle counters, the 3425 fan remains off when operating in a standard semiconductor cleanroom environment, virtually eliminating particle generation. The 3425 has a flow rate of 50 L/Min, 1.77 ft3/min. The updated particle size channel is 0.5 µM-10 µM per 1 CFM.
