Myron L. DS and pDS Meters™

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.

Myron L® Company has two proven ways to measure such impurities. Our DS Meters™ provide fast, accurate, on-the-spot measurements of total dissolved solids (TDS) or conductivity. 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.
