Yokogawa Releases OpreX Environmental Monitoring System for Pharmaceutical and Medical Device Industries

Tokyo, Japan - October 23, 2020

Yokogawa Electric Corporation (TOKYO: 6841) announces the October 23 global release of the OpreX™ Environmental Monitoring System for the pharmaceutical and medical device industries. The new product is a data collection and recording system that records and manages environmental data such as temperature, humidity, and room differential pressure in pharmaceutical and medical device manufacturing, testing, and storage areas. This system makes use of Yokogawa paperless recorders that comply with Good Manufacturing Practice (GMP*1), Quality Management System (QMS*2), and other regulatory requirements and are installed at multiple locations around a plant. The new system reduces risk and aids pharmaceutical and medical device manufacturers in the performance of strict and efficient environment monitoring that ensures compliance with the various regulations and guidelines on operations at manufacturing sites.

Development Background

In manufacturing, testing, and storage areas at pharmaceutical and medical device plants, the recording and management of environmental data such as temperature, humidity, differential room pressure, and particle count must be done in compliance with GMP, QMS, and other regulations that seek to ensure the correctness, comprehensiveness, completeness, and secure storage of this data*3. To streamline the management of environmental data measured at multiple locations in a factory, a unified approach is needed. Although data acquisition and storage could be performed by a general-purpose monitoring and control system, such a system would need to be configured to comply with regulatory requirements of various industries. Such a system would also have risk management problems because the data would be collected directly from sensors, and thus any kind of failure, such as power failure, sensor malfunctioning, or recorder capacity exhaustion could affect a broader scope of data. To address such issues, Yokogawa has developed the OpreX Environmental Monitoring System for the pharmaceutical and medical device industries.


This system consists of Yokogawa paperless recorders*4, a data server, and monitoring PCs.

Domain environment

  1. Compliance with regulatory requirements
    As required by the FDA's 21 CFR Part 11 and other electronic recording and signature regulations, the following functions are provided with the OpreX Environmental Monitoring System: a user management function, a function that prevents the rewriting, deletion, or falsification of recorded data files, an audit trail function, a time synchronization function, a backup restoration function, and an archive retrieval function. This ensures that the recorded data is correct, comprehensive, complete, and stored securely.
  2. Data collection and long-term storage
    This system's paperless recorders can be installed at multiple locations around a plant, reducing the risks that come from having all data stored in one central location. The data from the recorders is stored on a highly secure data server using a file format that helps prevent and detect any tampering of data. For backup storage, each recorder is equipped with an SD card function. In response to requests for data by auditors or other individuals, users need only to access and provide the relevant file.
  3. Real-time monitoring
    If a data error is detected by a monitoring PC, the PC will display an alarm message, issue an audible alarm, and/or send an email, depending on the paperless recorder setting. In addition, the data that has been collected by a paperless recorder can be accessed from any web browser.
  4. Computerized System Validation (CSV)*5
    The paperless recorders, data server, and monitoring PCs used in this system undergo a CSV assessment that complies with GAMP5*6, a de facto global CSV standard, before shipment to the customer.

Major Target Markets

Pharmaceutical and medical device industries


  • Recording, storage, monitoring, and management of environmental data, such as temperature, humidity, differential room pressure, particle count, etc. in production, testing, and storage areas
  • Recording, storage, monitoring, and management of temperature and humidity data from freezers and thermo-hygrostats
  • Recording, storage, monitoring, and management of data such as temperature, pressure, etc. for devices used in manufacturing processes

*1 Standards for production and quality management of the manufacturing of safe and effective pharmaceuticals. Each country sets its own regulations and guidelines.
*2 Standards for production and quality management of the manufacturing of safe medical devices and pharmaceuticals for in-vitro diagnostics. As with GMP, each country sets its own regulations and guidelines, including Japan's QMS ministerial ordinance on production management and quality management standards for medical devices. In addition, the ISO 13485 standard is applied internationally.
*3 The Ordinance for Enforcement of the Pharmaceutical Affairs Act specifies how documents on test results should be prepared. It requires test results that raise doubts about effectiveness and safety to be thoroughly examined and documented in a complete and comprehensive manner and requires the keeping of records that contain supporting information.
*4 GX10, GX20, GP10, GP20, and GM10 recorders in Yokogawa's OpreX Data Acquisition family are equipped with an optional security function that complies with the FDA's 21 CFR Part 11 regulations on electronic records and signatures and the ER/ES guidelines of Japan's Ministry of Health, Labour and Welfare
*5 Inspection work that is conducted when introducing computerized systems to make sure that there is no problem with hardware/software development, design, commissioning, operation, availability, etc.
*6 Based on GAMP®5: Risk-Based Approach to GxP Computerized Systems, it is the latest version of the Good Automated Manufacturing Practice (GAMP) standard on CSV procedures published by the International Society for Pharmaceutical Engineering, Inc. (ISPE).
