Glass-lined pH Probes

Long-lasting and low-maintenance

pH probe overview

The pH value is one of the most important and commonly measured values in many fields of industrial production. The stability of the entire production process can be increased by regulating the pH value in a targeted way. Thanks to their maintenance-free operation and long service lives, robust, glass lined pH-electrodes are a cost-effective option for continuous use.

These electrodes feature Pfaudler’s pH-sensitive, pH glass lining which reacts to H+ ions in liquid media, thus making them suitable for pH measurement.

Pfaudler pH probes are available with two different pH-measurement principles: „absolute pH-measurement principle“ and „relative pH-measurement principle“.

pH probe type 03

  • Absolute pH-measurement principle
  • Separate electrolyte vessel needed
  • Pfaudler Heavy-Duty Design
  • Perfect for use in chemical and other process industries with rough mediums
  • Can be mounted into vessels/reactors or in pipes directly in the product flow
  • Ex-certification

The pH probes type 03 are available in a rod design (with a flange in different lengths) and also in a ring design. More

pH probe type 18

  • Relative pH-measurement principle
  • No separate electrolyte vessel needed
  • Pfaudler Heavy-Duty Design
  • Perfect for use in chemical and other process industries with rough mediums and in food & beverage industry
  • Can be mounted into vessels/reactors or in pipes directly in the product flow
  • Without Ex-certification

The pH probe type 18 is available in a rod design (with a length of 144mm) and with common process adapters. More

pH probe type 40

  • Relative pH-measurement principle
  • No separate electrolyte vessel needed
  • Pfaudler Heavy-Duty Design
  • Perfect for use in chemical and other process industries with rough mediums
  • Can be mounted into vessels/reactors or in pipes directly in the product flow
  • Ex-certication

The pH probes type 40 are available in a rod design (with a flange in different lengths) and also in a ring design. More

pH probe type Reiner

  • Absolute pH-measurement principle
  • Separate electrolyte vessel needed (stainless-steel)
  • Pfaudler Hygenic Design
  • Perfect for use in food & beverage industry (EHEDG-certificate)
  • Can be mounted into vessels/reactors or in pipes directly in the product flow
  • Without Ex-certification

The pH probe type Reiner is available in a rod design (with a length of 120mm) and with common process adapters. More
