<p>A terbidimeter has a simple and strong structure not to often malfunction and reduced number of seal parts, thereby obtaining excellent long-term stability. A cylindrical sensor head (4) forming a measurement space (Sa) is formed of a light-transmittable material. The side wall (42) of the sensor head (4) has receiving spaces (Sb1-Sb3) for receiving a light source (5), a transmitted light detector (6), and a scattered light detector (7). The inner surface of the side wall (42) of the sensor head (4) becomes an optical window (M1) for inducing inspection light (L1) to the measurement space (Sa), an optical window (M2) for inducting transmitted light (L2) to the transmitted light detector (6), and an optical window (M3) for inducing scattered light (L3) to the scattered light detector (7).</p> |
