Abstract
A salimeter based on the electric conductivity measurement of an objective liquid solution and devised so as to give the salinity of the solution instantly without any correction or adjustment with respect to a temperature of the solution. The apparatus is divided into a main electronic circuit portion and a measuring probe or probes to be detachably connected to the main circuit portion through a connecting cable. Each of the probes is provided with a pair of electrodes and a temperature sensor, both to be immersed directly in an objective solution, while the main circuit portion comprises a first means for measuring the conductivity between the electrodes, a second means for generating a temperature effect compensation signal according to an output from the temperature sensor and an arithmetic divider for outputting a ratio of the measured conductivity to the temperature effect compensation signal. The ratio, which gives the conductivity of the solution at a predetermined standard temperature, is converted to a corresponding value of salinity and then displayed on a display unit.
