The First Optical Dissolved Oxygen Sensor Granted ATEX Approval

The VisiPro DO Ex, from Hamilton (USA), is the only optical dissolved oxygen (DO) sensor for use in explosive environments. VisiPro optical technology improves the measuring performance and simplifies maintenance. Improvements compared to conventional electrochemical (amperometric) sensors include flow independence, rapid start-up with no polarisation time, and simplified maintenance.

The smart sensor with integrated transmitter enables direct communication to the process control system via two wire 4-20 mA standard signal or digital HART. All relevant sensor data including calibration and diagnostic information are stored in the sensor head, simplifying calibration and maintenance. Additional wireless communication directly from the sensor to your computer simplifies laboratory calibration, configuration, and maintenance.
