AGRI-METER tests water, soil and fertilizer pH and salinity easily and quickly.
AGRI-METER tests water, soil, and fertilizer pH and salinity easily and quickly. Readings are given directly in millimhos/conductivity.
ALKALINITY tests are critical to proper pH adjustments of water and floral preservative solutions.
CONDUCTIVITY TERMINOLOGY: 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.
