A connected optical particle counter for continuous, real-time monitoring of cleanrooms and controlled environments — wireless, battery-powered, and ISO 21501-4 compliant for Grade A* to D / ISO 5–8 classifications.

SafyrOPC is designed exclusively for cleanroom and controlled-environment use, dedicated to continuous monitoring of Class A* to D, ISO 5–7–8 environments across pharmaceutical, biotechnological, medtech, hospital, microelectronics and aerospace applications. Based on optical particle counting with laser scattering technology, each unit is factory-calibrated with an individual certificate. The device communicates over proprietary LoRa with mains power or an internal battery (12 hours to 7 days of autonomy depending on configuration); the sensor itself is also available wired, for integration into tools and equipment. SafyrOPC received the Prix de l'Innovation at ContaminExpo / SallesPropres 2023.
Every monitoring point reads continuously, closing the blind spots left by sequential manifold systems.
LoRa communication (869.5 MHz / 2.4 GHz) with mains or battery power — no complex wiring or tubing to install.
High-efficiency filtration at discharge keeps the surrounding environment clean.
Detects movement or tampering of the device for added process security.
Compact, smooth-surface design compatible with surface disinfectants and H₂O₂ decontamination cycles.
Annual sensor swap of roughly 10 minutes, with no extended calibration downtime.
