Claims

[Claims for Utility Model Registration] A container for storing a liquid, a brewet part attached to the upper side of the container part, an air inlet for pushing up the liquid from the container part to the brewet part, and a brewet part. In a titration analyzer equipped with an automatic brewet equipped with an outflow pipe with a valve that allows liquid to flow out from the air pump, the air pump is connected to the air inlet, and air is introduced between the air pump and the inlet. detecting the characteristic values of the liquid in the titration vessel into which the liquid flowing out from the outflow pipe is introduced; a titration sensor; a liquid level sensor that detects the liquid level in the brewet section; a detection signal from the liquid level sensor is input;
It is equipped with a liquid input switch, and when the liquid input switch is operated, an air pump is activated to input the liquid into the brewet section, and when the liquid reaches a predetermined level, the signal from the liquid level sensor is used to It is equipped with a liquid injection controller that opens the air electromagnetic valve and stops the air pump, and a titration switch that receives the detection signal of the titration sensor, and when the titration switch is operated, the liquid electromagnetic An automatic titration analyzer comprising: a titration controller that opens a valve and closes the liquid electromagnetic valve based on a signal from the titration sensor.
