pH Electrodes

HORIBA has been a pioneer in pH measurement technology since 1950, when it introduced Japan’s first glass electrode pH meter. Today, HORIBA continues to lead the way with advanced pH electrode designs that deliver precision, reliability, and versatility. Whether you’re using a bench or portable meter, HORIBA pH electrodes—including the renowned LAQUA series—are engineered for high accuracy and compatibility.

Our refillable pH electrodes (excluding the 9651-10D GEL FILLED model) require the HORIBA pH reference filling solution #300 for optimal performance. The standard HORIBA pH combination electrodes come with a 1-meter cable and a BNC connector, making them suitable for most pH meters on the market. For applications requiring temperature compensation, our 3-in-1 pH glass body electrodes feature an integrated thermistor, allowing real-time temperature measurement and automatic compensation to ensure accurate pH readings under varying conditions.

Choose HORIBA for a dependable pH electrode that keeps pace with your evolving measurement needs.
