Find conductivity cells with the critical specifications you want In addition to the features mentioned above, look for temperature compensation, temperature sensors, water resistance and output of total dissolved solids (TDS). Note that conductivity cell construction can vary, using graphite, titanium and stainless steel. Weigh these features as you make your selections from a conductivity cell distributor.

I recommend:  At the GlobalSpec website, you can find a database of 105 companies that specialize in conductivity cells and related instruments. Select a few firms and investigate their products. Topac carries a variety of 2-electrode and 4-electrode cells. Compare the features and prices of their offerings as you determine what you want.

Sample conductivity cells with different mounting options Mounting style directly impacts ease of use. Consider in-line, insertion, flow-through and hand held devices for your projects. Order samples of each option from a conductivity cell vendor.

I recommend:  David Inotek Instruments distributes Amber Science conductivity cells. They have a variety of "dip type," "flow thru," "multipurpose" and "flow" cells as well as a micro flow cell. Check the product information for further details. For information on thermal conductivity cells, check out the ThermTest website. There you can review the descriptions for products to determine if thermal conductivity cells best meet your needs. Sample a model from the online catalog.

Buy your conductivity cells at competitive prices Different features, specifications, and materials influence conductivity cell prices, which vary widely. Make a list of 'must-have' and 'nice-to-have' features and specifications. Then, use the list to determine pricing.

I recommend:  JUMO Process Control specializes in electrical instruments. Conductivity cell supplier Thermo Fisher Scientific carries an extensive list of devices with different features. Review the features and correlate the differences in pricing.
