-Product Overview

The GLI differential ORP/pH sensor adopts patented differential technology (patent number US6395158), with three electrodes replacing traditional dual electrodes and a built-in preamplifier for accurate and reliable performance. The ORP/pH sensor can be made of Ryton or PEEK corrosion-resistant materials to cope with strong alkaline environments or reduce thermal distortion, and the salt bridge can be replaced to extend the life of the ORP/pH sensor.

-Operating principle

The GLI differential ORP/pH sensor is based on differential electrode measurement technology, using three measuring electrodes instead of the dual electrodes in traditional pH sensors. The difference in pH value between the measuring electrode and the standard electrode relative to the background electrode of the third solution. At the same time, a preamplifier is used to amplify the output of each electrode, and the current signal is converted into the pH value of the water sample, which is the measurement result of the pH sensor.

-Application industry

The GLI differential ORP/pH sensor is suitable for monitoring industrial processes such as petroleum, pharmaceuticals, and papermaking; Measure, display, and transmit pH and temperature values during water treatment processes.

-Features and advantages

The GLI differential ORP/pH sensor adopts differential patented technology (patent number US6395158), with three electrodes replacing the traditional pH sensor's dual electrodes to reduce drift and error, resulting in accurate and reliable results.

The built-in preamplifier has strong anti-interference ability, and the pH sensor output signal is high fidelity.

The GLI differential ORP/pH sensor can be selected from Ryton or PEEK materials to measure special water samples. The Ryton material pH sensor has good compatibility with strong alkaline substances, reducing maintenance and downtime. PEEK material pH sensor reduces thermal distortion.

Built in replaceable salt bridge extends the lifespan of GLI differential ORP/pH sensor.

The pH sensor is compatible with Hash SC200 or SC1000 universal controllers, plug and play, with multiple installation methods to choose from.
