Digital Conductivity Meters are reliable and accurate test instruments for measurement of Conductivity of aqueous solutions. They measure Conductivity in five ranges. The Resolution is 0.1 ?S/cm and o.1 ppm respectively, in the lowest range. The cell constant is flashed on a digital display& can be adjusted from the front panel. The instruments have the “Check” facility to calibrate the instrument. These instruments are ideal for monitoring salt contents in water and soluble salts in soils. They are extremely useful instruments for agriculture and soil analysis labs, swimming pools, fertilizer plants, petroleum refineries, textile plants etc.
