ISO 21501-4-calibrated OEM particle-counting module for controlled environments
Sensor SafyrOPC is an OEM optical particle-counting module designed for integration into cleanroom and contamination-monitoring equipment. It provides particle counts across five size channels with a controlled 2.83 L/min sampling flow.
Each sensing module is individually calibrated according to ISO 21501-4 and supplied with a calibration certificate linked to its serial number.
Building a reliable particle-counting instrument requires control of sampling flow, particle-size channels, counting performance, calibration, electronics and communication.
Sensor SafyrOPC provides manufacturers with a compact and individually calibrated OEM sensing module that can be integrated into their own cleanroom, process-monitoring or contamination-control equipment.
The sensing module provides a controlled nominal sampling flow of 2.83 L/min for defined particle-counting conditions.
Particle counts are provided across five defined size channels for integration into the final system's monitoring and analysis functions.
Each module is individually calibrated and supplied with a certificate linked to its serial number.
The compact module can be integrated into custom electronics, enclosures, communication systems and monitoring equipment.
Each Sensor SafyrOPC module is characterized individually.
Calibration is performed according to the applicable particle-counter requirements of ISO 21501-4.
Each module is supplied with an individual calibration certificate linked to its serial number.
ISO 21501-4 calibration applies to the Sensor SafyrOPC module. The conformity and performance of the final instrument remain dependent on its sampling architecture, electronics, software, enclosure, integration and validation.

Sensor SafyrOPC is supplied with the technical and metrological documentation required to evaluate the module and integrate it into a particle-counting instrument.
Each module is supplied with its own certificate, linked to its serial number.
Flow, counting efficiency, false-count rate and size channels are documented in full.
Monodisperse latex-sphere calibration bench, traceable to a NIST certificate.
Detection efficiency and false-count behaviour are characterized as part of the calibration process.
Sensor SafyrOPC provides the calibrated particle-counting module at the core of the final device. Sampling inlet design, tubing, enclosure, electronics, communication, software, calibration management and maintenance must still be designed according to the intended application.
TERA Sensor supports the integration of the sensing module into custom particle-counting equipment. Through TERA Tronics, projects can also be supported through electronics development, prototyping, industrialization and series manufacturing.
No. Sensor SafyrOPC is an OEM sensing module designed for integration into a complete particle-counting instrument or monitoring system. TERA Sensor also offers a separate ready-to-use SafyrOPC instrument.
Sensor SafyrOPC provides individually calibrated particle-counting capability for integration into an instrument. Its use for cleanroom classification depends on the architecture, software, sampling system and validation of the complete instrument.
