Abstract

PURPOSE:To simplify a device an to expand its measurable concentration range, by conducting light source by photofiber. CONSTITUTION:In front of a light source 1, respective photofibers 15 are provided between a light-collecting lens 2 and a liquid 7 to be measured and also between the liquid 7 and a light-receiving element 11. By doing so, a light emitted from the light source 1 is once collected by the light-collecting lens 2, and after having been sent into the liquid directly by the photofiber 15, the transmitted light is introduced to the light-receiving element by the photofiber 15 to conduct measurement of turbidity of the liquid 7. And therefore, it is no longer necessary to use the light- collecting lens and a reflecting mirror for controlling of light passage, and the device becomes thus simplified, and at the same time, by enabling the light passage to be introduced freely, it becomes possible to shorten and extend the light passage length and also to expand range of measurement. Further, the effect can be further improved by protecting the photofiber 15 with a stainless steel tube 16 and a clear glass 17.
