The GroStar™ GS5-E ORP Electrode is a high-performance electrode designed for use with the GroStar™ GS1, GS2, and GS4 Pen Testers. When connected, the instruments automatically recognize the electrode and switch to ORP (Oxidation-Reduction Potential) measurement mode. This allows you to accurately measure the redox potential (ORP) of liquids, including nutrient solutions and other water-based solutions.

Equipped with a platinum sensor and double-junction design, the GS5-E ensures reliable and precise ORP measurements. The electrode is easy to attach without the need for additional tools, providing a convenient solution for quick and efficient testing.
