The EZO-Complete USB Dissolved Oxygen meter makes building a custom monitoring system easy. Simply connect the EZO-Complete to a PC and install the free Atlas Desktop software. Connect multiple EZO-Complete Dissolved Oxygen modules to read D.O. from multiple locations. Embedded systems engineers can use EZO-Complete Dissolved Oxygen with any USB-enabled microcontroller. EZO-Complete will create a virtual comport and is controlled using simple serial strings.
