TURBIDIMETER

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.

1. A turbidimeter comprising:
a closed-bottom cylindrical sensor head forming a measurement space for accommodating a sample; a light source for irradiating inspection light to the measurement space; a transmitted light detector for detecting transmitted light passing through the measurement space; and a scattered light detector for detecting scattered light scattered in the measurement space, wherein the sensor head is formed of a material having optical transparency, a side wall of the sensor head comprises accommodating spaces for accommodating the light source, transmitted light detector, and scattered light detector, and an inner surface of the side wall of the sensor head is configured to serve as: an inspection light optical window for guiding the inspection light to the measurement space; a transmitted light optical window for guiding the transmitted light to the transmitted light detector; and a scattered light optical window for guiding the scattered light to the scattered light detector.
