Automatic UV Analyzer UVT-300

This automatic UV analyzer makes full use of the features of the popular UVT-101, and is designed for even greater maintainability and ease-of-use.

Features

Principle of Measurement

Light from a light source lamp passes through the sample cell, and is split into 2 directions using a half-mirror, and the amount of transmitted UV and visible light is detected by photocells. Part of the light from the lamp directly enters a photo cell on the light source side, and the amount of radiated UV and visible light are detected. By processing these 4 detection signals, it is possible to measure turbidity-corrected UV absorbance (UV-VIS) with automatic correction for the effects of changes in the turbidity of the sample water, and changes in the emission intensity of the light source lamp.
