The Myron L RO-1 Meter is easy to use and requires no special training. Simply pour the sample into the cell cup and press the button. ppm/TDS is immediately indicated on the color-coded scale (models without the color band dial are
also available). No temperature adjustments are ever required!
The unique circuitry of the 750 Series II Conductivity Monitor/controllers guarantees accurate and reliable measurements. Drift-free performance is assured by “field proved” electronics, including automatic DC, offset compensation and highly accurate drive voltage.
Both AG-5 and AG6/PH AGRI-METERS are calibrated in millimhos, the term most widely used by growers to express electrical conductivity. Some charts may read in other units called micromhos. However, since one millimho equals 1,000 micromhos, the conversion is easy. Parts per million (ppm) is also sometimes used. Conductivity/ppm fertilizer concentration tables can be obtained from your supplier, consultant, or university advisor.
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.
