Ei’s Deluxe TDS Meter and Digital TDS Meters are accurate test instruments for measurement of TDS of aqueous solutions. They use the latest microcontroller technology to measure the TDS in five ranges from 200ppm to 1000ppt. The appropriate range is automatically selected by the instrument. The Resolution is 0.1 ppm in the lowest range. The cell constant is flashed on a digital display and can be adjusted from the front panel. Facility is also provided for automatic measurement of cell constant with a known standard solution. The auto temperature compensation facility is available in model 652 using the temperature probe.


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 lab, swimming pools, fertilizer plants, mineral water plants, petroleum refineries, textile plants etc.
