Myron L Water Quality Monitors and RO System Controllers The unique circuitry of our 750 Series II Conductivity, TDS and Resistivity Monitor/controllers guarantees accurate and reliable measurements. Drift-free performance is assured by "field proven" electronics, including automatic DC offset compensation and highly accurate drive voltage.

Since Temperature Compensation is at the heart of accurate water measurement, all Myron L Monitor/controllers feature a highly refined and precise TC circuit. This feature perfectly matches the water temperature coefficient as it changes. All models are corrected to 25°C. The TC may be disabled to conform with USP requirements.
