Regular use of the conductivity standards in factories and laboratories guarantee instruments are properly calibrated at all times for accurate readings. Placing probes into the solution with an identified transfer ability, the equipment settings can be adjusted prior to testing. The equipment maintenance permits estimations of impurities and ion levels present in samples. Meeting industry regulations, the solutions are created under strictly controlled conditions for complete working stability and reliability.
