SODIUM CARING DEVICE

摘要

An embodiment of the present invention relates to a sodium caring device. The purpose of the present invention is to rapidly and accurately display the concentration value of sodium contained in a sample by measuring the salt concentration and temperature of the sample. The sodium caring device comprises: a printed circuit board which is mounted inside a body; a battery which is mounted inside the body and is connected with the printed circuit board; at least one electrode which is installed at one end of the body, whose one end is connected with the printed circuit board, and whose the other end is submerged in a sample or is in contact with the sample; and a temperature sensor. The printed circuit board comprises: a power supply unit which supplies power; a key selecting unit which selects a motion; a sample information detecting unit having a conductivity measuring unit which detects the electroconductivity value of the sample measured by the electrode, and a temperature measuring unit which detects the temperature value of the sample measured by the temperature sensor; a memory unit which stores the electroconductivity value according to the temperature value of the sample to the concentration value of sodium or salt in advance; a control unit which compares the measured electroconductivity value and temperature value of the sample with the electroconductivity value according to the temperature value to the concentration value of sodium or salt, stored in the memory unit, and calculates the concentration value of sodium and the concentration value of salt corresponding to the measured electroconductivity value and temperature value of the sample; and a display unit which displays the concentration value of sodium and the concentration value of salt corresponding to the calculated electroconductivity value and temperature value of the sample.
