The present invention is the current which is output from the noise detection unit hydrazines of temperature changes in the process and by compensating them, the liquid hydrazine to accurately measure a very small amount of hydrazine measuring apparatus, vertically moved up and down to a concentration in the liquid hydrazine disposed in a pair of positive (+) electrode and a negative (-) by detecting a current flowing between the electrodes detecting a hydrazine, hydrazine detector measuring the temperature of said temperature measuring part, wherein the current is detected by the noise detecting unit hydrazines voltage signals the current-voltage conversion portion, the current-voltage converting unit outputs the voltage signal to a constant level by a low-noise amplifier amplifying and filtering the aftermath of which the part and the low-noise amplifier and the voltage signal received from the wake part according to the detected concentration of hydrazine, wherein the temperature measuring unit, the measured temperature stored in the memory according to the change of temperature of the electrode current measured in a standard solution, with reference to the detected concentration of hydrazine is corrected, the signal processing and control signal processing and control unit for generating a command measuring device comprising a hydrazine provides the infinitesimal. [Reference numerals] (100) Hydrazine detection unit; (110) Temperature measurement unit; (120) Current-voltage conversion unit; (130) Amplification and aftereffect uinit; (140) AD conversion unit; (150) Signal process and control unit |
