The general-purpose pH/ORP sensor is designed to meet the broadest range of applications in the industry. It has the widest temperature operating range of any general-purpose sensor and is the first to function at sub-zero temperatures, providing accurate measurements in applications from -10 to 100 degrees C, according to the manufacturer. Each sensor is equipped for both ¾-inch and 1-inch mounting, allowing it to fit in smaller pipes, giving optimum mounting versatility in insertion, submersion and flow-through applications. The unit features the company’s patented sensor glass formulation, which has been field-proven in premium sensors designed for rugged environments. The formulation exceeds industry standards and resists cracking. In addition, a unique Teflon double-junction reference electrode protects the sensor from poisoning ions. The complete encapsulation of the sensor eliminates leakage or high humidity problems found in other pH/ORP sensors. The unit is a combination sensor including pH, ORP (Oxidation Reduction Potential) and temperature within the sensor body. It is designed to measure aqueous solutions in pipelines, open tanks, or ponds. The sensor is compatible with all of the manufacturer’s analyzers as well as those from other manufacturers.
