Conductivity measurement by Inductive conductivity sensors (CAT#: STEM-PPA-0017-WXH)

Inductive sensors are using two electromagnetic coils usually encased in a polymer ring. An alternating voltage is applied to the driving coil, which induces a voltage in the receiving coil. The induced current is influenced by the conductance of the solution.

Quality control: Surveillance of feedwater purity, control of drinking water and process water quality, estimation of the total number of ions in a solution or direct measurement of components in process solutions.

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.
