Frequently Asked Questions

ACS specializes in two-electrode contacting style sensors. With plans to add four-electrode designs soon.
Electrical conductivity sensors measure the concentration of a dissolved substance in an aqueous fluid or solution.
The materials of construction largely depend on the needs of our customers. The standard sensors are 316 stainless steel electrodes, with Teflon insulators and FDA-approved o-rings. At the same time, our high-temperature sensors are 316 stainless steel electrodes, with PEEK insulators and specialty high-temperature o-rings. Other materials of construction are available. Ask the factory for more.
The cell constant you need depends on your desired measurement concentration value and the analyzer the sensor is connected to. The lower the conductivity measurement, the lower the cell constant. Or the higher the conductivity measurement, the higher the cell constant. Refer to the owner’s manual of the analyzer you are using. Often there are measurement range recommendations for the cell constants.
The available cell constant depends on the sensor design of choice. We have sensors with cell constants of K=0.01, 0.1, 1.0, 2.0, and 10.0. Ask the factory for more details on which line of sensors and constant is best for your needs.
Our standard sensors come with a Pt1000 temperature compensator element, and other options are available. Ask the factory for more.
The owner’s manual of the device you are connecting the sensor to will tell you what TC is needed in the sensor. Most modern analyzers require a Pt1000 temperature compensator.
