Myron L EP-10 DS Conductivity Meter – 4 Range 0-10/100/1000/10000uS. APPLICATIONS: Boilers & cooling towers Deionization Reverse osmosis Chemical concentrations Printing fountain solutions Swimming pools & spas Water pollution control Wastewater 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 MetersT provide fast, accurate, on-the-spot measurements of Total Dissolved Solids (TDS) or Conductivity. PDS MetersT 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, some of which are listed above. Unique Field-Tested Design Our unique, durable, field-tested design has evolved over more than 40 years, making Myron L instruments among the most reliable and popular of their kind in the world. 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. EP-10 is a multi range conductivity meter that reads in uM/uS DS Conductivity Meter Ranges: 0-10, 100, 1000, 10,000 µM/µS. 1, 3, 4 or 5 depending on model 2-12 pH (pDS Meters only).
