Conductivity measurement by Contacting conductivity sensors (CAT#: STEM-PPA-0016-WXH)

The contacting conductivity probes consist of two electrodes made of metal (stainless steel or titanium) that are in contact with the given solution whose conductivity we need to measure.

They are ideal for use in cooling towers and boilers, reverse osmosis equipment, and other non-oily applications.

1. Use a conductivity standard solution (usually potassium chloride or sodium chloride) to calibrate the meter for the range that you will be measuring.
2. Rinse the probe with distilled or deionized water.
3. Select the appropriate range beginning with the highest range and working down. Read the conductivity of the water sample. If the reading is in the lower 10 percent of the range, switch to the next lower range. If the conductivity of the sample ex ceeds the range of the instrument, you may dilute the sample. Be sure to perform the dilution according to the manufacturer's directions because the dilution might not have a simple linear relationship to the conductivity.
4. Rinse the probe with distilled or deionized water and repeat step 3 until finished.
