Key benefits

Compliant w​ith major regulatory regimes

The heart of the Vaisala viewLinc monitoring system is the viewLinc software that ensures data integrity with an audit trail, access controls, encryption, and authority levels to fulfill regulatory requirements. Compliance is simplified with validatable software, mapping/qualification capabilities, encrypted data and audit trail, optional protocols and GxP documentation, ICH-compliant calibration options. The viewLinc software reports on historical temperature, humidity, or other measurement data comply with GxP guidelines and standards, FDA 21 CFR Part 11, EU Annex 11, ICH, etc.

Industry-best sensors, widest range of parameters

Choose from Vaisala’s selection of data loggers, transmitters and probes. Add almost any modbus-enabled device to viewLinc software for unlimited measurement flexibility.

Operates independently, scales easily

For quick, simple validation, viewLinc software operates independently of other control and monitoring systems. viewLinc’s validated data can also be connected via API or OPC to other systems. Scale up easily—from one or two data loggers to thousands. With eleven languages, viewLinc is ideal for multi-site use and global monitoring. The system can integrate with Active Directory to simplify User management, can manage multiple time zones and report in the local time.

Fully configurable

With a variety of alarm notification options and reports, the system is fully configurable to meet your needs. viewLinc sends alarm notifications through multiple methods, including: onscreen, email, SMS, alarm towers, relay to alarm service, and voice calls. Data is logged continuously and autonomously at the point of measurement ensuring that data is never lost to power or network downtime. Devices can connect to the viewLinc software via Ethernet, PoE, Wi-Fi or Vaisala's secure long-range wireless technology: VaiNet.

Fully supported

Service options include full life-cycle support, including installation, validation, and calibration -- either on-site, or in our accredited calibration laboratories. Select a maintenance agreement that maximizes your system’s availability, lifespan, and performance. Support includes 24/7 access to technicians online or by phone as well as on-demand access to eLearning, documentation and other resources.

Designed for usability and compliance

viewLinc's software interface has been optimized for ease of installation and use. Onscreen guidance shows you how to complete tasks. Reporting options include pre-configured reports that are easy to customize and can be delivered automatically on user-selected schedules. The system makes audits and inspections easy with reliable environmental monitoring data.
