Salinity range

Seawater 0~100.0 ppt

TDS range (f is TDS fctor)

0-9999ppm or10.0~160*f ppt; f is TDS factor

Temperature range

-5~60.0 C

There are 3 calibration ranges, 1413uS calibration solution is used for 0-199uS operating range, 12.88mS is used for 2.0-19.99mS and 111.8mS calibration solution is used for 20-160mS. Seawater, for example, at 35ppt is 53.065mD/cm (1.0264 relative specific gravity (sg)). Calibration solutions are sold separately.
