This article explains the cleanroom shift from spot checks to continuous, in-operation particle monitoring. It outlines why spot checks miss dynamic spikes and suffer from small sampling volumes and broken evidence chains. It then shows how continuous monitoring delivers earlier detection, better explainability, and audit-ready data. Readers learn the essential monitoring loop—Measure → Alert → Verify → Investigate → CAPA—plus practical ways to avoid...

PMS 31 is a remote, cleanroom-grade particle counter designed for continuous, in-operation monitoring. Delivering a standardized 28.3 L/min (1 CFM) sampling flow, it improves statistical confidence in high-grade areas (ISO 5 / Grade A/B) and detects short-lived contamination events faster. The instrument is calibrated to ISO 21501-4 for traceable, comparable results and integrates easily with EMS/BMS/SCADA systems via RS485 (Modbus RTU). With long-life optics and...
