All Myron L® handheld instruments are factory calibrated with NIST traceable Standard Solutions having specific conductivity/ppm values. Myron L® Company Standard Solutions are made under strictly controlled conditions using reagent grade salts. These salts are mixed with deionized water having a resistivity of at least 5 megohms-cm purity.
Myron L® Company Standard Solutions have an accuracy of ±1% based on values published in the International Critical Tables and traceable to the National Institute of Standards and Technology.
Myron L® conductivity instruments and monitor/ controllers are calibrated to read in ppm/442, ppm/ NaCI, or microsiemens. All three values are listed on our Standard Solutions.
The relationship among these standards can be seen in the table and graphs that follow.
The advanced “isolated” circuitry of the 720 Series II pH/ORP Monitor/controllers guarantees accurate and reliable measurements — completely eliminating ground-loop and noise issues. The unique sensor preamp allows for longer distances between the sensor and the Monitor/controller without the loss of accuracy or reliability
Ultrameter II model delivers the performance of ±1% of reading (not merely full scale). This high level of accuracy has been achieved through advanced four-electrode conductivity cell technology, a unique pH/ ORP sensor, and powerful
microprocessor-based circuitry. With displayed values of up to 9999, the full four-digit LCD ensures resolution levels
never before possible in such affordable instruments. Factory calibrated with NIST traceable solutions, each
Ultrameter II may be supplied with both certification of traceability and NIST traceable solutions for definitive calibration
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.
