Link2Site® Web Monitoring and Control Solution

Reduce costs and improve odor and corrosion treatment with real-time monitoring and control

Link2Site® Web Monitoring from Evoqua provides operators with remote access to hydrogen sulfide data for real-time monitoring and responsiveness to changing site conditions. The Link2Site web platform interfaces with Evoqua’s VaporLink® Hydrogen Sulfide Monitor and VersaDose® Dosing Controller for comprehensive performance monitoring and dosing control.

Operators can connect to the system from any location to program dosing rates, manage inventory, set system alarms, and view and download trending graphs and charts to analyze system performance . The result is a more efficient use of chemicals, reduced labor requirements, and better odor and corrosion control.
