Vaisala viewLinc Continuous Monitoring System
The Vaisala viewLinc Continuous Monitoring System is a complete environmental monitoring, alarming and reporting platform for pharmaceutical facilities, biotechnology production, cleanrooms, laboratories, warehouses, hospitals, blood banks, cold rooms, freezers and other critical environments.
At the centre of the system is viewLinc Enterprise Server 5.2, the current on-premises software platform. It receives measurements from Vaisala data loggers, transmitters and compatible Modbus devices, then provides real-time displays, multi-stage alarms, secure records, audit trails and automated reports.
viewLinc operates independently from process-control and building-management systems, preserving a separate monitoring record for quality and compliance. Validated data can also be made available to authorised external systems through optional OPC UA or the viewLinc API.
Vaisala viewLinc integrates monitoring software, data loggers, sensors and alarm communication in one scalable system.
Why Choose Vaisala viewLinc?
- Continuous Environmental Records: Measurement devices record critical parameters automatically around the clock.
- Gap-Free Data: Compatible data loggers retain measurements locally during temporary network or server interruptions and transfer stored records after communication returns.
- Multi-Stage Alarming: Threshold, device, communication and system alarms can be routed to responsible personnel.
- Secure Audit Trails: System activity, configuration changes and alarm acknowledgements are documented for review.
- Controlled User Access: Roles, permissions and authentication options restrict access to authorised functions and monitoring locations.
- Automated Reporting: Historical, alarm and audit-trail reports can be generated, customised and delivered on a schedule.
- Scalable Architecture: Expand from a small system to thousands of monitored locations and multiple sites.
- Flexible Connectivity: Supports Ethernet, Power over Ethernet, Wi-Fi, secure VaiNet wireless and compatible Modbus instruments.
- Validation Support: IQ/OQ protocols, GAMP-based documentation and professional validation services are available.

GxP Data Integrity and Regulatory Support
viewLinc is designed for regulated environments where monitoring records must remain complete, attributable, reviewable and protected from unauthorised change.
| Quality Requirement | viewLinc Capability |
|---|
| FDA 21 CFR Part 11 |
Access controls, electronic records, audit trails and controlled system functions support compliant implementation |
| EU GMP Annex 11 |
Validation documentation, security, audit trails, data retention and controlled access support regulated computerised systems |
| Data Integrity |
Secure records, device memory, audit trails and role-based permissions help protect measurement history |
| Calibration Traceability |
Compatible devices are available with calibration traceable to SI units through national metrology institutes or accredited laboratories |
| Validation |
IQ/OQ protocols and optional GAMP-based GxP documentation support documented system implementation |
| Audit Readiness |
