Water quality is critical to the efficiency and performance of water treatment applications and to the longevity of its associated equipment. Sodium measurement is one of the most common techniques that achieves accurate and rapid response at any time to detect possible salt contaminations that are known to be contributory factors in the stress and pitting of corrosion resistant steel.
Sodium concentration monitoring has therefore become one of the most essential water quality determinants throughout various water treatment applications. Depending on the application the following instruments should be included as Key Instrumentation:
