pH combination electrodes, ProcessLine

These electrodes are low maintenance sensors for heavy duty process applications in the chemical industry. They are ideally suitable for measuring media with extreme ionic strength - whether boiler feed water or brine - also in strongly oxidizing acid and alkali containing media.

• Low-maintenance electrodes: no electrolyte topping up or installation of complicated pressure sequence control required
• Pinhole diaphragms, so reference electrode is not polluted or blocked
• Duralid electrolyte with high KCl content combines very long working life with rapid and stable measurements
• Proven H membrane glass with very low alkali error and optimized spherical shape
• Integrated pressure compensation cushion
