摘要： The present invention is one that makes it possible to continuously measure the resistivity of a liquid sample with accuracy as well as preventing the deterioration of the liquid sample associated with measurement, such as change in quality, and relates to a resistivity-measuring circuit C that measures the resistivity in order to sense the deterioration of the liquid sample. The resistivity-measuring circuit C is one that calculates the resistivity of the liquid sample by detecting voltage generated between an outer electrode and an inner electrode, and between the outer electrode and the inner electrode, applies square wave AC voltage having an amplitude of 1 V to 42 V and a frequency of 0.5 Hz to 30 Hz.

摘要： The present invention is intended to provide a turbidimeter having a simple and sturdy structure which is hard to break and exhibits excellent long-term stability by reducing a number of sealing positions, wherein a cylindrical sensor head forming a measurement space is formed of an optically-transparent material. A side wall of the sensor head has accommodating spaces for accommodating a light source, transmitted light detector, and scattered light detector. An inner surface of the side wall of the sensor head is configured to serve as: an optical window for guiding inspection light to the measurement space; an optical window for guiding transmitted light to the transmitted light detector; and an optical window for guiding scattered light to the scattered light detector.
