The output of all pH electrodes varies with temperature in a manner predicted by the Nernst Equation. When Automatic Temperature Compensation (ATC) is necessary for your installation, Sensorex can supply a system to match your requirements.

All pH and ORP electrodes in the S600 and S222 series are designed for easy maintenance, using cartridge-type combination electrodes and quick-disconnect BNC connectors. Electrode installation and removal can be done in just a few seconds and no tools are needed.

Sensorex supplies pH buffers as dry powder ready to mix with 100 mL of DI water and pre-mixed ready-to-use color coded liquids--blue for 10 pH, red for 4.01 pH, and yellow for 7 pH. Several other useful chemicals are available. Electrode storage solution will help you to maximize the storage life of all your electrodes such as reference electrode refill solutions as well as several types of gels are available.

All pH circuits require a high impedance preamplifier to which the electrode connects. This preamplifier is available to come either as a part of the the meter or as a separate external component. Many process controllers require external preamplifiers to match the electronic circuit's impedance gain to the actual pH electrode.

Low cost, two-wire, 4-20 mA transmitters for pH interface to PLC and dataloggers

pH Simulators will help you easily to troubleshoot problems with your pH control system and quickly identify which component in the system is causing your difficulty.

Use these fittings to mount our standard 12 mm diameter electrodes into pipe Tee fittings or for submersion into tanks.

Sensorex supplies many types and styles of special connectors to permit you to use our electrodes with most makes and models of pH meters, transmitters, and controllers.
