AquaLynx® 250 RO

The RODI Systems AquaLynx® Model 250 RO is a compact data acquisition, monitoring, and control system designed specifically for commercial and light industrial RO applications. It takes advantage of the latest microprocessor technology and differs from most other low-cost control systems in that it offers data logging and remote monitoring capabilities.

One of the unique features of the AquaLynx® Model 250 RO is its compatibility with RODI Systems AquaGraph software. AquaGraph is a Windows application which allows the user to observe and control the Model 250 RO remotely in real time. It also allows the user to download historic data and logged alarms either remotely via modem or locally via direct serial connection.
