Abstract: Disclosed is an apparatus for measuring salinity of interstitial water in a soil sample, the apparatus including: an air supplier that generates a stream of high-pressure air; an air nozzle from which the high-pressure air, supplied from the air supplier, is ejected; a soil-compressing tank into which the high-pressure air, ejected from the air nozzle, is introduced and which compresses a soil sample contained therein to squeeze interstitial water from the soil sample; and a water tank which collects and stores the interstitial water drained from the soil-compressing tank and in which a salinity-measuring sensor for measuring salinity is installed to measure salinity of the interstitial water.
