7301 remote particle counter 0.3 µm @ 0.1 CFM
The Particles Plus 7301 remote particle counter measures particles from 0.3 μm to 25 μm in diameter with a flow rate of 2.83 LPM (0.1 CFM) and is the most versatile remote particle counter available. The 7301 can be placed freely as a stand-alone instrume
The Particles Plus 7301 remote particle counter offers the precision and reliability essential for monitoring controlled environments. This instrument is specifically developed for cleanroom technology professionals who require accurate particle measurements according to international standards.
Advanced monitoring and reporting
The Particles Plus 7301 remote particle counter measures simultaneously on six user-selectable channels, ranging from 0.3 μm to 25.0 μm. Thanks to the built-in sensors for temperature and relative humidity, you get a complete picture of environmental conditions. The system supports direct reporting on the 4.3-inch colour touchscreen according to ISO 14644-1, EU GMP Annex 1, and FS 209E. For data redundancy, the device stores up to 45,000 time-stamped records, which are easy to export via Ethernet, USB, or optional wireless connections.| Particle size range | 0.3 to 25.0 μm |
