PMT® 9301 PoE
The 9301 PoE Particle Counter is a high-precision instrument designed for accurate monitoring of airborne particle concentrations in cleanrooms, laboratories, and industrial environments. Covering a particle size range from 0.3 to 25.0 μm with a constant flow rate of 0.1 CFM (2.83 LPM), the 9301 provides reliable and precise particle counting critical for quality control and regulatory compliance. The device not only meets international calibration standards ISO 21501-4 and JIS B9921 but exceeds them, making it suitable for demanding environments where maximum measurement accuracy is essential. A key feature of the 9301 is its flexible particle size channel configuration, offering six user-selectable channels, expandable up to 30 channels. This allows for detailed and differentiated particle analysis, tailored to the specific requirements of each application. The integrated critical nozzle and flow sensor ensure a stable flow rate and consistent performance, even when using an external vacuum source, maintaining accuracy and operational efficiency throughout extended use. The 9301 is designed for seamless integration into building automation and facility monitoring systems. It supports MODBUS TCP/IP via RJ45, as well as Power over Ethernet (PoE) and Wi-Fi (802.11 b/g) connectivity, enabling efficient data transfer, remote monitoring, and real-time control. These features provide operators with a robust solution for continuous oversight of particle concentrations and air quality in sensitive environments.With its durable construction, customizable particle channels, and easy integration into modern automation systems, the 9301 PoE Particle Counter offers a reliable and precise solution for airborne particle monitoring. It is ideally suited for cleanroom applications, production facilities, and other critical environments where maintaining strict air quality standards is a priority. With the 0.1 CFM flow rate, this is ideal for industries such as automotive, electronics, and aerospace.
