pDS Meters

pDS Meters provide fast, accurate, on-the-spot measurements of total dissolved solids (TDS) or conductivity plus pH.


No water supply is completely pure. Every industrial, commercial or natural source contains dissolved solids or salts. These impurities contribute to scale, corrosion, poor taste, and environmental pollution that endanger animal and plant life.

pDS Meters™ test Conductivity or TDS plus pH. Readings from their highly stable circuitry help assure product quality, prevent equipment damage and verify in-line instrumentation in a wide range of applications.

Lightweight and compact, Myron L’s pDS Meters are also tough, with rugged, taut-band meter movements.
