Refex Sensors Ltd products

Maintenance free REFEX Scries 399 electrodes arc designed for pH measurement in rugged applications. Series 399 combination electrodes feature the patented REFEX Contact Window, a non-porous, hard ionically conductive interface/bar her to prevent reference electrode electrolyte loss and poisoning. Typical application areas: Petro/Chemical. Pulp & Paper, Water Treatment, UPW.

The REFEX Extraction bypass/flow cell arrangement is designed to retrofit to existing 1/2" 316 stainless steel pipe work. The process connections are 1/2" Swageioc type compression tittings in/out. liquid Earth/Solution ground is integral in the flow cell. The REFEX Electrode is a 12 x 120 mm combined electrode with inbuilt PtlOOO or Pt100 temp, comp device. The electrode process fitting is PG13.5 free turning electrode cap. Electrode has IP 68 fixed cable (1m/3m/5m/10m lengths) hard wiring back to the pH instrument.

REFEX pH electrode for PR10 Yokogawa Retractable Immersion System. “Long Life” Refex pH Combination Electrode PG13.5 Free turning Head Cap. Non Porous Reference “ cannot be fouled or poisoned” resistant to all Oil and Gas and Petrochemical processes.

REFEX manufactures a range of probes designed to be direct replacements for YokogawaTM 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.

The REFEX Reference System has a higher impedance than conventional porous junctions therefore the impedance setting needs to be changed on the Yokogawa instrument.
