Digital Conductivity Meters are higly precise testing instruments for measurement of conductivity/TDS/Salinity of Aqueous solutions. The Conductivity and TDS are meassured five ranges. The resolution is 0.1 �S/cm and 0.1 ppm respectively, in the lowest range. The cell constant is flashed on a digital display from the front panel. The instruments have the "Check" facility to calibrate the instrument. These instrument are ideal for monitoring salt content in water ans soluble salts in soils. They are extremely instruments for agriculture and soil analysis labs, swimming pools, fertilizer plants, petroleum refineries, textile plants etc.
