Product details

The Signet 2724-2726 pH/ORP Electrodes are designed with a patented reference electrode and DryLoc® connector. Their large area PE reference junction and pathway provide total reference effectiveness and ensure long-lasting service. The DryLoc® connector is an ideal solution for quickly pairing the sensor to its 2760 preamplifier or the 2750 sensor electronics. Its gold-plated contact points are designed to prevent any unwanted leakage.

Ryton® threaded sensor body offers different sensing elements for flat pH, bulb pH, or flat ORP, thus providing a wide range of chemical compatibility for various applications. Not just that, two optional sensing versions are also available to make HF and low conductivity measurements convenient. The quick temperature response is available in either a PT-1000 or 3KΩ temperature sensor and allows compatibility with all Signet pH/ORP instruments.

Signet’s PT-1000 and 3KΩ temperature sensors provide quick and accurate temperature response, making it the perfect choice for all your pH/ORP instrument needs. These sensors offer a wide range of compatibility with different instruments and are designed to ensure reliable performance in any application. With their superior accuracy, these sensors allow you to accurately measure temperatures in a variety of environments at an affordable price.
