Abstract

PURPOSE: To improve the measuring accuracy of an electrolyte analyzer by mutually twisting shield conductor and signal wire to reduce the noise.
CONSTITUTION: An ion selecting electrode 20 makes contact with specimen liquid 16 to be detected with electrolyte contained in a specimen container 17 together with comparison electrode 29 at measuring time. The signal wire 41 of the comparison electrode 29 is connected to an earth terminal 28. The infinitesimal signal voltage produced between the electrode 20 and the electrode 29 is introduced via twisted wires into an amplifier 21. The external induction noise transmitted by leakage from shield coated material 25 is carried on the twisted wire but becomes substantially equal value by the twisting effect to be amplified by differential amplifier 21 to be cancelled at the effect of the external induction at the output.
