The ST-774 PortaPanel is a prefabricated panel ideally suited for those desiring to use the ST-774 Ultra-Low Dissolved Oxygen Sensor with local display and data acquisition in a portable fashion for oxygen measurement (ie. de-aerator performance studies). The PortaPanel is pre-mounted on an easy-carry, self-standing 316L stainless-steel panel. It arrives with the ST-774 sensor, flow-cell and appropriate water sample/calibration gas flow hardware.
The panel also comes equipped with an integrated UC-50 Display/Data Logging Terminal for connected to the ST-774 via RS-485 Modbus offering live data display, calibration interface and data logging of the sensor. The UC-50 offers a contact relay output and has RS-485 Modbus and (1) 4-20mA outputs for passing the sensor value onto another device. The UC-50 also offers Bluetooth 5.0 capability for those desiring to use the uPyxis mobile or desktop apps for wireless calibration and diagnostics of the Pyxis sensor connected.
