Novel double-channel fluorescence-method dissolved oxygen detector

Abstract

A novel double-channel fluorescence-method dissolved oxygen detector is characterized by comprising a first sensor for detection of the content of dissolved oxygen by adopting a fluorescence quenching principle, a second sensor for detection of data of the dissolved oxygen, and a controller including a double-channel input module connected with the first sensor and the second sensor, a main control module connected with the input module, a display and key module connected with the main control module, a storage module connected with the display and key module, an output module connected with the display and key module, a control module connected with the output module, and a power supply module for supplying power for each module in the controller. By adopting the above technical schemes, the novel double-channel fluorescence-method dissolved oxygen detector has the beneficial effects that the detector can realize online continuous measurement, is guardless, realizes real water quality automatic monitoring, at the same time, detects two channels of the dissolved oxygen, reduces costs, and has the characteristics of small amount of maintenance, Chinese digital output, stable function and high accuracy.

Description

technical field [0001] The invention relates to the field of detectors, in particular to a novel dual-channel fluorescence method dissolved oxygen detector. Background technique [0002] At present, with the improvement of people's living standards and the advancement of urbanization, water pollution in cities is becoming more and more serious.
