MET ONE 3400+ Series Cleanroom Routine Environmental Air Particle Counter
Our new MET ONE 3400+ Series Portable Airborne Particle Counter allows users to load their routine environmental monitoring SOP sampling map and sampling configuration for each location directly into the counter, so that the SOP becomes an interactive sampling map directly on the counter screen to guide users doing daily sampling. This helps reduce training requirements and sampling data errors/omissions.

Our new MET ONE 3400+ Series Portable Airborne Particle Counter allows users to load their routine environmental monitoring SOP sampling map and sampling configuration for each location directly into the counter, so that the SOP becomes an interactive sampling map directly on the counter screen to guide users doing daily sampling. This helps reduce training requirements and sampling data errors/omissions.
Accessed remotely via a web browser, features such as review/approve workflow, SOP version control and electronic record export are all in the counter – there’s no external software needed. Secure on-board searchable/filterable Audit Trail provides fast reporting during audits combined with Microsoft Active Directory for User Name and Password control for log-on and electronic signatures to support 21 CFR Part 11 compliance.
Customized Interactive Electronic SOP Maps
Using a web-browser interface, load your SOP map into the counter, mark sample locations, and define SOP sampling requirements for each.
Interactive Tracking
Onscreen instructions help operators navigate your map and perform sampling according to the SOP. Location names turn green after sampling, making it easy to track progress at a glance.
Electronic Records Straight from the Counter
The MET ONE 3400+ can provide electronic records straight from the counter via USB, wired Ethernet or built-in WiFi.
Web-browser SOP Version Control and Review & Approve Workflow
Managers can remotely review daily monitoring progress including all sample results via a web-browser. Remote SOP configuration and version control is also available for administrators, as well as remote review & approve, electronic signature sign-off and electronic record export for supervisors – all via web-browser.

Ensure compliance and patient safety using total particle air counting in sterile compounding facilities
April 17, 2025 at 16:00 BST / 17:00 CEST / 11:00 EDT / 08:00 PDT
With the critical role that sterile compounding plays in patient care, ensuring compliance with USP <797> standards and mitigating risks from airborne particulate matter is essential for all sterile compounding operations — including 503A pharmacies, hospitals, infusion centers, and 503B outsourcing facilities. For this reason it is crucial to have adequate implementation to uphold aseptic standards, reduce risks, and protect patients.
In this educational webinar, Dr. Amy Summers, 503A & 503B Compounding Consultant at Restore Health, will give a comprehensive overview of the importance of total particle air counting. Hear real-life case studies that highlight best practices that you can implement to ensure you meet regulatory requirements and maintain a sterile environment.
Key learning objectives:
- The why: Why is total particle air counting crucial for sterile compounding facilities? Understand its role in contamination control, risk reduction, and patient safety as outlined in USP <797>.
- The how: Learn how to use total air particle counters, including best practices for accurate air sampling in ISO-classified areas (ISO 5, 7, and 8).
- Avoiding pitfalls: Learn how to avoid common errors and challenges in air counting, such as incorrect sampling, misinterpretation of data, and maintenance oversights.
- Real-world case studies: Hear examples of sterile compounding facilities implementing robust particle monitoring programs, including lessons learned and benefits achieved.
- Regulatory alignment: Understand how to align particle monitoring programs with the updated USP <797> requirements, focusing on maintaining ISO air quality classifications and proper documentation.
