Conductivity is a measure of the ability of a fluid to conduct an electrical current. In water this ability is due to the presence of various ionized substances in solution. Conductivity measurements usually include temperature compensation.

To help you choose the right conductivity measurement system for your specific liquid applications needs, follow these recommended steps.

Step 1: Determine Application Requirements

Defining the following variable before building your system will ensure peak performance from your sensors, electrodes and instruments.

• Measurement range
• Installation requirements
• Pipe size and material
• Chemical compatibility of all wetted parts to process chemicals
• Hazardous location requirements
• System specifications (such as temperature and pressure)
• Performance requirements of sensor / electrode
• Fluid particulates
• Viscosity of fluids

Step 2: Select Sensor / Electrode Technology

Based on the application requirements, choose a sensor or electrode. Then, determine your signal output requirement to allow you to match the right instrument.

Step 3: Choose Instrument

Choose a conductivity / resistivity or multi-parameter instrument. All units are available in 1/4 DIN panel or field configuration and are available with digital, analogue, or analogue / digital display. Various retrofit adapters and mounting accessories are also available.

Step 4: Determine Installation Requirements

We offer a wide selection of installation fittings to suit select analytical insertion sensor and electrodes. These fittings are specifically designed to ensure the proper placement of the sensor or electrode in the system to achieve accurate readings.
