Description

Technical Field

[0001] This utility model relates to the field of ultraviolet analyzer technology, and in particular to an online ultraviolet analyzer for analyzing chlorine content. Background Technology

[0002] Ultraviolet (UV) analyzers come in many series, including three-in-one UV analyzers, darkroom UV analyzers, and photographic UV analyzers, each with different applications. For example, the C4000 series chlorine concentration analyzer can detect chlorine concentrations from ppm to percentage levels. This instrument is designed using the UV-Vis optical principle. The C4000 is equipped with a dual-beam optical sensor, which measures the intensity of light absorbed by the process medium. Typically, during operation, the internal electronic components of a UV analyzer generate heat, which is dissipated through heat dissipation vents to ensure the analyzer's operational stability.

[0003] The heat dissipation holes on the housing of existing ultraviolet analyzers lack any protective measures. External dust enters the ultraviolet analyzer through the heat dissipation holes and settles on its internal electronic components and sensors, affecting the heat dissipation of the electronic components and the measurement accuracy of the ultraviolet analyzer, thereby affecting the analysis results. Therefore, we propose an online ultraviolet analyzer for analyzing chlorine content to solve the above problems. Utility Model Content

[0013] The above technical solution is adopted: the snap-fit ​​component includes a snap-fit ​​interface opened on the mounting port and a snap-fit ​​plate provided at the bottom of the mounting plate, which facilitates the snap-fit ​​of the mounting plate onto the mounting port.

[0014] Preferably, the filtering component includes a frame, and a filter screen is disposed inside the frame.

[0015] The above technical solution is adopted: the filter component includes a frame, and a filter screen is installed inside the frame to further prevent dust from falling into the interior of the ultraviolet analyzer.
