Yokogawa equivalent pH probes

Refex manufactures a range of probes designed to be direct replacements for Yokogawa brand electrodes in the field.  Refex probes connect directly to Yokogawa analyzers to provide end users with enhanced measurement capabilities and extended life through utilization of the unique Refex reference cell interface.

Refex reference sensors are designed for arduous applications particularly where fouling or poisoning conditions exist. The reference uses a highly stable non-porous polymeric interface instead of a traditional porous liquid junction as used by all conventional Yokogawa reference electrodes.  The active reference area is the whole of the outside surface of the electrode and this super large contact area means that the electrode is supremely resistant to coatings.  Poisoning effects are eliminated because the polymeric reference material is conductive to ions but not porous; the reference can operate electrically but electrolyte and process fluids are not exchanged.
