PMT® 9301P PoE
The 9301P PoE Remote Particle Counter is an advanced and reliable instrument designed for precise airborne particle monitoring in cleanrooms, laboratories, and industrial environments. Measuring particles from 0.3 to 25.0 μm at a constant flow rate of 0.1 CFM (2.83 LPM), it delivers highly accurate particle concentration data for critical air quality control applications. Users can select from six standard particle size channels, expandable up to 30 channels, allowing detailed and differentiated particle analysis across multiple size ranges. This flexibility is particularly important for stringent monitoring requirements in GMP-regulated cleanrooms and other controlled environments. The 9301P features an integrated pump, eliminating the need for an external vacuum source, which simplifies installation and enhances operational flexibility in areas with limited space or specific airflow requirements. The device meets international calibration standards ISO 21501-4 and JIS B9921, ensuring measurement accuracy and compliance for quality-critical applications. For seamless integration into facility monitoring or building automation systems, the 9301P supports MODBUS TCP/IP over RJ45, Power over Ethernet (PoE), and Wi-Fi (802.11 b/g), enabling efficient data transfer, remote monitoring, and real-time air quality reporting. These communication options allow the particle counter to be incorporated into networked monitoring systems, supporting continuous oversight of particle concentrations across multiple locations. With its robust construction, intuitive configuration, and versatile connectivity, the 9301P PoE Particle Counter provides a dependable solution for airborne particle measurement. It ensures precise monitoring of air quality in cleanrooms, production facilities, and other sensitive environments, offering both reliability and easy integration for operators who require accurate, real-time particle data. With the 0.1 CFM flow rate, this is ideal for industries such as automotive, electronics, and aerospace.
