mS 12.88 STANDARD – 9016 PPM, 8 OZ, 16OZ, 1 Gallon and Cases
CONDUCTIVITY STANDARDS – EC meters (electrical conductivity) measures soluble salt concentration in a primarily two scales. Most common in the hobby sector is an interpretation of total dissolved solids (TDS) as parts per million (PPM). Most accurate and used in science and industry is Seiman’s displayed as mS (milli seimans) or uS (micro seimans).
Genesis Labs solutions offers both values based on a conversion factor of one mS = 700 ppm which is intended to represent the average agricultural salts of a fertilizer solution.
