Aquametrix 2300 Web-Enabled Analytical Controller for pH, ORP, Conductivity, and Flow

Get the functionality of a PLC and SCADA at the price of a transmitter! The Aquametrix 2300 controller accepts a total of four inputs from 4-20 mA output probes and three square wave inputs from pulse instruments, like paddlewheel or magnetic flowmeters. Four relay outputs are programmable from any of the seven inputs or via the difference of two analog inputs. More inputs or outputs can be added with an optional expansion card.

The web-integrated 2300 controller can send e-mail or text notifications, and lets you view controller status from any secure web browser. You can even use a web-based setup wizard to configure the controller from a laptop PC, cell phone, or tablet.
