Abstract
The invention discloses a device for measuring the liquid absorption coefficient under the condition of an external electric field. The device comprises an incident light source, a sample pool, a power supply, electrode plates and a measuring unit, wherein the sample pool is of a transparent rectangular structure; in addition, the thicknesses of each side edge are equal; the electrode plates comprise a first electrode plate and a second electrode plate which are mutually parallel; the first electrode plate is fixedly arranged at the inner side of the first side edge of the sample pool and is connected with the positive electrode of the power supply; the second electrode plate is fixedly arranged at the inner side of the second side edge of the sample pool and is connected with the negative electrode of the power supply; the incident light source is arranged at the outer side of the third side edge of the sample pool; generated incident light rays are incident along the direction vertical to the electric field through a light transmission hole formed in the third side edge; the measuring unit is arranged at the outer side of the fourth side edge of the sample pool and is positioned on a light path of the incident light rays; the third side edge and the fourth side edge are mutually parallel. The device has the advantages that the electrode plates are arranged in the sample pool; the uniform electric field can be exerted on liquid to be tested, so that the change of the liquid absorption coefficient under the effect of the external electric field is accurately measured.
