Water Treatment Sensors – pH and ORP Electrodes

Clean water is a necessity for residential, commercial, and industrial applications. However, water in its natural form may be contaminated due to various reasons and hence requires additional treatments to make it potable. Before deciding upon the right treatment, two water quality parameters – pH and oxidation reduction potential (ORP) are tested. Walchem offers high-quality, carefully designed pH ORP sensors for various water treatment applications. These sensors are compatible with Walchem pumps and controllers.

Types of pH ORP Sensors Offered by Walchem

At Walchem, we provide the following types of pH ORP sensors for various water treatment applications.

  • WDS Differential pH/ORP: These sensors are designed to perform in applications where other electrodes fail. They offer reliable and long-lasting performance in various challenging municipal and industrial applications. They can transmit signal up to 3,000 feet.
  • WEL pH/ORP: These are cost-effective differential pH ORP electrodes are designed for industrial applications. Our WEL series pH ORP sensors come with easily replaceable electrode cartridges, which are offered in different styles, including flat surface, bulb, HF resistant, and low ionic strength pH cartridges and flat platinum or rod ORP cartridges.
  • High Temperature and Pressure pH/ORP Electrodes: These pH ORP electrodes are designed to function in challenging environments, where other pH ORP sensors fail. They can handle pressure up to 500 psi at room temperature and temperatures up to 275°F (135°C) in low-pressure installations.
