Zusammenfassung:	The invention discloses a device and method for testing liquid osmotic pressure. The test device includes a permeating part, a liquid adding part, a sight glass part and a pressurization part. A to-be-tested liquid is added into the permeating part by the liquid adding part, a reference liquid undergoes membrane permeation and is mixed with the to-be-tested liquid, then the mixed liquid enters the sight glass part, and the pressurization part is employed to transport gas. After the liquid level is maintained at the sight glass part for a period of time, the pressure value is read, thus obtaining the osmotic pressure value. The invention provides a novel method and device for testing the osmotic pressure, and the influence of concentration polarization is also taken into consideration at the same time of effective testing the osmotic pressure.
