Electrodes, pH, ORP Laboratory

  Overview

A wide variety of pH and ORP Electrodes are available with glass or epoxy bodies, with many options including specialized sensors such as Sleeve Junction, Side Arm Refill, Spear Tip, Flat Tip and Reduced Tip.

Combination electrodes have reference electrodes. Plastic electrodes are rugged and are preferred for field use, while glass electrodes are standard in the laboratory, are easy to clean, and can tolerate somewhat higher temperatures.

Ion Selective Sensors and other electrodes from Rose Scientific are listed on separate pages.

Features of the pH and ORP Electrodes:
  • Direct replacements available for all major brands
  • Epoxy and glass bodies
  • Numerous options such as Tuff-Tip, Triode (with temperature compensation), reduced body diameter and various connectors
  • Sealed and refillable references
  • Fast and accurate response
