PROBLEM TO BE SOLVED: To provide an automatic horizontal hydrometer for accurately measuring the specific gravity of a sea water sample. SOLUTION: The automatic horizontal hydrometer is provided with a container 1 and a floating measuring indicator. The container 1 is divided into an upper-end handle part 12 and a lower measuring chamber 2. The pointer is pivoted outside the measuring chamber and freely rocked. A dark tube is provided in the inside of a side wall of the container. An equilibrium suspending point is provided at the upper end of the handle part. The equilibrium suspending point is a rocking-free support. A middle part of the floating measuring indicator is provided with a weight having a biased center of gravity. In the automatic horizontal hydrometer, by rotation-freely arranging the weight 10 having a biased center of gravity in a circular hole at the middle part of the floating measuring pointer and combining a movable hook with the rocking-free support and the weight having a biased center of gravity, it is possible to accurately fix the hydrometer to an absolutely horizontal location and to easily and accurately perform original setting of the hydrometer in a manufacturing process.
