Description
Global Water’s WQ401 Dissolved Oxygen Sensor is a rugged and reliable water oxygen measuring device. The WQ401’s sensor is attached to 25 ft of marine grade cable, with lengths up to 500 ft available upon request. The sensor’s output is 4-20 mA with a three wire configuration. The sensor’s electronics are completely encapsulated in marine grade epoxy within a stainless steel housing. The unit uses a removable shield and dissolved oxygen element for easy maintenance.
Record and Control:
You can add recording and controlling capabilities to your 4 - 20 mA sensors with either a Global Water’s GL500 Data Recorder and Global Water’s PC320 Process Controller. The GL500 connects to the dissolved oxygen sensor’s 4-20 mA output to record data, and the PC320 Controller connects to the sensor’s output to control pumps or alarms. Additionally, we offer other data loggers with wireless telemetry capabilities for remote data access and long-term monitoring. Contact us to get more information on our integrated solutions.
