pH & ORP Sensors

pH & ORP Sensors
Hach offers a wide variety of process pH and ORP sensors to meet your application needs. The differential sensors use an innovative, unique electrode technology which results in greater accuracy, less drift, and less frequent calibration. The LCP sensors are designed to meet more rigorous industrial applications. And for those users on a budget, Hach offers a low cost line of Combination pH/ORP sensors.
