PURPOSE: A salinometer having a shock switch inside is provided to install a switching device for manipulation inside a housing, thereby simplifying a manufacturing process excluding an extra waterproof process for the switching device. CONSTITUTION: A salinometer (100) includes a main body (110), a sensor part, an indicating part (130), and a switching device (150). The inner side of the main body is waterproof from outside. The sensor part at one end of the main body detects the salinity of a target. The indicating part at one surface of the main body indicates a measured result from the sensor part. The switching device inside the main body electrically contacts by a shock from an external shock body, and then switches the driving of the sensor part and the indicating part. |
