☆ Adopt international advanced solid dielectric and large area PTFE liquid junction. Not easy to block, easy to maintain

☆ The long-distance reference diffusion path greatly prolongs the service life of the electrode in harsh environments

☆ The newly designed glass bulb increases the bulb area and prevents the formation of interfering bubbles in the internal buffer, making the measurement more reliable

☆ Adopt PPS/PC shell, upper and lower 3/4NPT pipe thread, easy to install, no need for sheath, saving installation cost

☆ The electrode adopts high-quality and low-noise cables, which can make the signal output longer than 20 meters without interference

☆ No need to supplement the dielectric, low maintenance

☆ High measurement accuracy, fast response and good repeatability

☆ Ag/AgCL reference electrode with silver ion

☆ Correct operation and long service life

☆ Can be installed sideways or vertically in the reaction tank or pipeline

☆ The electrode can be used interchangeably with similar foreign electrodes

Basic principle of PH electrode

The electrodes used in PH measurement are also called galvanic cells. The primary battery is a system whose function is to convert chemical energy into electrical energy. The voltage of this battery is called electromotive force (EMF). This electromotive force (EMF) consists of two half-cells. One of the half-cells is called the measuring cell, and its potential is related to the specific ion activity; the other half-cell is the reference half-cell, usually called the reference electrode, which is generally connected to the measuring solution and connected to the measuring instrument .
