Key Benefits

User friendly software, real-time data & alarming
Secure web-access to real-time trends and graphical overviews of all monitored locations. viewLinc's learn-as-you-use interface guides you through tasks and functions. Tours introduce you to common features, saving time and levelling the software learning curve. Drill down into monitored areas in a dashboard view to see data for your devices over any time period. Receive alerts on monitored environments through email or SMS.
Data integrity ensured
Months of data can be retained in data logger memory, depending on the device model and sample intervals. viewLinc preserves data integrity in many ways; first, data is saved to a secure database on the server. Onboard power and memory in measurement devices preserve all data during network or power outages and allows data backfill once connection to the network is restored.

viewLinc 5.0 installs easily to an existing network via a combination of connectivity options, including Ethernet, Power over Ethernet, Wi-Fi, or VaiNet - Vaisala's proprietary long-range wireless technology. The monitoring devices self-identify within the viewLinc software and come with easy-to-use configuration templates. Tours introduce common tasks, providing useful onscreen guidance, and embedded tooltips provide immediate user assistance making viewLinc easy to learn.
