Conductivity Probes
Conductivity Probes

Conductivity probes measure the electrical conductivity of liquids. These probes typically consist of electrodes that immerse into the liquid to assess its ability to conduct electricity, which correlates with ion concentration and purity. Conductivity probes provide real-time data for providing optimal conditions and compliance with industry standards. Browse our selection below or contact us to speak with a product expert.

Conductivity Transmitters
Conductivity Transmitters

Conductivity transmitters measure and transmit electrical conductivity levels in liquids. These transmitters convert conductivity measurements into standardized electrical signals (such as 4-20 mA) for monitoring and control systems. Conductivity transmitters provide real-time data to optimize processes and ensure compliance with regulatory standards. Browse our selection below or contact us to speak with a product expert.

This rugged titanium workhorse is available in 4 different cell classes for a truly versatile sensor transmitter. The ProCon® C450 series double electrode conductivity sensor transmitter has been proven to operate seamlessly in industrial applications up to 200,000µS/cm. Measuring specific conductivity of aqueous solutions is becoming increasingly important for determining impurities in water. The measurement accuracy is greatly affected by temperature variation, polarization of the contact electrode surface, and cable capacitance. The ProCon® line of analytical sensor transmitters have been designed for difficult industrial applications and to outperform even in extreme conditions. The 2-wire 4-20mA, 4-wire or 4-20mA + RS485 output options simplify calibration and communication with remote displays and controllers.
