Are ph machine electrodes the same?

Currently there are three main types of pH electrodes: liquid electrodes, gel electrodes and solid electrodes.

Liquid pH electrodes

Liquid electrodes, such as the InPro2000 series, are fillable liquid electrodes, which are the most classically designed, high-quality, and widely applicable electrodes in the history of the invention of pH electrodes, and are suitable for a wide range of industrial process measurements.

Gel pH Electrodes

Gel electrodes are upgraded liquid electrodes, such as the InPro3250 series, which are low-maintenance and suitable for on-line measurements in demanding applications, and which are designed for long-lasting use after several cycles of CIP (Cleaning-in-Place) and SIP (Steam In-Place).

Solid State pH Electrodes

Solid state electrodes such as the InPro4260 series, DXK series electrodes, InPro4010, InPro4501, and InPro4550, which are more commonly used in the chemical industry, utilize a new solid state polymer reference electrolyte that provides accurate pH measurements while maintaining a long lifespan even in the most harsh industrial environments. These electrodes are more commonly used in the chemical industry and utilize a new solid polymer reference electrolyte for accurate pH measurements and long life, even in the harshest industrial environments.

PH electrode, also known as pH probe, pH sensor, English name pH electrode or pH sensor, is the part of the PH meter that is in contact with the measured substance, and is used to measure the electrode potential of the device.
