Conductivity instruments are a convenient way to determine the parts per million of total dissolved solids (ppm/TDS) in boilers, cooling towers, reverse osmosis systems, etc. Although the International Unit (Sl) of measuring conductivity is the microsiemens/ cm (also known as micromhos/cm), a direct reading in ppm/TDS is sometimes preferred.
Myron L conductivity instruments and monitor/controllers are calibrated to read in ppm/442, ppm/ NaCI, or microsiemens. All three values are listed on our Standard Solutions.
