PURPOSE:To prevent precipitation, solidification of fine particles in liquid specimen and keep a sensitive part constantly clean, by installing an oxygen gas measuring electrode in a specimen chamber led to a liquid path and allowing the sensitive part of electrode to contact with a magnetic rotor. CONSTITUTION:A specimen solution is introduced from a liquid path 20 leading to a specimen chamber 18, the chamber 18 having been provided with a magnetic rotor 21 inside. Specimen chamber 18 and electrolytic bath 15 are fixed on top of a vessel 23 containing a motor 22, and a magnetic body 25 is mounted on a shaft 24 of the motor 22. Upon driving the motor 22 and rotating the magnetic body 25, the magnetic rotor 21 inside the chamber 18 rotates as it rubs a diaphragm 17, a sensitive part of the oxygen gas measuring electrode. By this, clogging of the diaphragm can be prevented, even when a specimen liquid, such as blood which is prone to solidification is analyzed. |
