- Our digital pH sensors offer improved process reliability. Patent-pending perpetual
impedance diagnostics detect electrode faults in real-time without the need for a
solution earth, while our smart Reference Electrode Monitoring (REM) system
provides early warning notification of electrode poisoning.
- By connecting your sensor to one of our digital transmitters, you can ensure
that your sensor is replaced at the optimum time, saving money without
risking process control.
- Thanks to ABB’s EZLink fast connection technology, you can get quick
and easy access to a full range of sensor data, including diagnostics,
without the time and hassle typically associated with installing
and commissioning sensing systems.
Ideal for open channel applications, the UviTec UV254 probe is a submersible instrument installed directly in-situ. The UV254 probe must be connected to a UviTec controller for operation.
