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, 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. 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.

Accessories we recommend |
Standard Solutions: NIST Standard Solutions & pH Buffers All Myron L instruments are factory calibrated with Standard Solutions of known conductivity/TDS value and (when appropriate) with pH buffer values 4, 7 and 10. These solutions and buffers are traceable to the U.S. Government's National Institute of Standards and Technology. Periodic recalibration with the appropriate Standard Solutions and pH Buffers will help maintain the accuracy of your instrument. See the table above for recommendations. Note: pH 7 Buffer is especially important and should be used every 1- 2 weeks. |
Range Extender: Increases the conductivity/TDS range by a factor of 10 when inserted into the sample filled cell cup. Not available for model 512T10. Model: RE-10 |
Porta-Kit (pDS only): Hard foam-lined case with 2 oz. bottles of pH Buffers 4, 7 and 10 and conductivity Standard Solution. Model: PK3 for models M6/PH, T2/PH & T6/PH; Model: PK7 for EP11/PH. |
Replacement pH Sensor: Replacement pH Sensor is a unique non-refillable KCl gel-filled combination pH electrode, featuring a porous liquid junction. Model: RPY |
NIST Certification: Certificates are available that confirm NIST traceability of an instrument (Order #MC) or Standard Solution/pH Buffer (Order #SC). Note: Both MC Certificates and/or SC Solution Certificates must be specified when placing instrument/solution orders. |
Model EP-11/pH Our most popular pDS model features four conductivity ranges and a 2-12 pH range |
