Choosing a sensor that is well-suited for your application can improve measurement accuracy and extend sensor lifetime. That’s what makes glass-body sensors such a strong fit for municipal water and wastewater applications. They are designed to perform well in those unpredictable chemical environments due to the naturally inert properties of glass. 

Sensorex’s GT-Series glass-body PTFE-junction pH electrodes offer that sought-after reliable performance in unpredictable chemical environments. The inert properties of the glass bodies and PTFE junctions resist clogging and coating for stable readings and minimal cleaning in most applications. According to Dominic O’Donnell, marketing director for Sensorex, models are available with DIN or VarioPin connectors.

“The GT-Series will work well in drinking water or wastewater applications, but also can be utilized in applications such as hydroponics, or industrial water treatment,” he says. “Sensorex has over 50 years of experience in the design and manufacture of pH electrodes, so you know you are getting time-tested quality.”

The basic GT100 models feature 120 mm insertion length and are available in single- or double-junction reference. They are designed to be easy to use and perform reliably in applications such as hydroponics, gardening and education, with temperature ranges from 23 to 212 degrees F. 

The advanced GT200 (120 mm insertion length) and GT300 (225 mm insertion length) feature a double-junction, salt ring reference for enhanced stability over time. They can be supplied with built-in temperature elements, and are designed for use at temperatures from 23 to 266 degrees F and pressures from 0 to 6 bar. They are ideal for testing samples with high temperatures such as those found in industrial wastewater. A double salt ring reference design ensures constant reference concentration for increased stability over time.

“Having models available with built-in temperature sensors ensures the temperature compensation required for accurate measurements in changing conditions,” O’Donnell says. “In addition, having detachable cables with either S8 or VarioPin connectors ensures broad compatibility with existing installations.”

All models offer accurate and reliable measurements across the full pH scale (0-14). They serve as an instantly ready, drop-in replacement for common 12 mm installations. 714-895-4344;
