Ei’s Digital Salinity Meter model 671 is an ideal instrument for measurement of Salinity of aqueous solutions. They use the latest microcontroller technology to measure the Salinity in three ranges from 2 ppt to 50 ppt. The appropriate range is automatically selected by the instrument. The Resolution is 0.001 ppt to 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.

This instrument is ideal for monitoring salt contents in water and soluble salts in soils. This is extremely useful instrument for agriculture and soil analysis labs, swimming pools, fertilizer plants, mineral water plants, petroleum refineries, textile plants etc.
