DS & pDS Meters™
TDS/Conductivity and pH Testing Instruments
Readings You Can Count On 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. Reliability Built In Breakage is one of the major causes of sensor failure in a typical pH or conductivity instrument. Myron L® instruments provide maximum protection for both the pH and conductivity electrodes inside the cell cup. The user-replaceable pH electrode features a chemical-resistant, porous liquid junction. Unique Field-Tested Design Our unique, durable, field-tested design has evolved over more than 55 years, making Myron L® instruments among the most reliable and popular of their kind in the world. They’re lightweight and compact, yet Myron L®’s DS and pDS Meters are also tough, with rugged, taut-band meter movements. Put our meters to the test. Even after years of rough field service, they’ll surpass your expectations of accuracy, reliability and simplicity.
