Multi-parameter water quality analyzer

Abstract

The invention discloses a multi-parameter water quality analyzer. The multi-parameter water quality analyzer comprises a hand-held controller and at least one intelligent sensor, wherein the hand-held controller comprises a battery, a battery management module, a display module, a first DC/DC (Direct Current) module, a second DC/DC module, a first central processing unit, a keyboard and a first analogue-to-digital interface; each intelligent sensor comprises a second central processing unit, a third DC/DC module, a second analogue-to-digital interface, a reference voltage source, a signal acquisition module and a sensor. The multi-parameter water quality analyzer is provided with a plurality of sensors, thus being capable of detecting parameters such as PH (potential of hydrogen), OPR (Oxidative Phosphorylation), electrical conductivity and dissolved oxygen content in water, comprehensively detecting the water quality and accurately judging the water quality; meanwhile, the detection part is separated from the observation part so that a user can observe the detected water quality parameters by use of the hand-held controller in the finite range without being restricted to a water quality detection site; the multi-parameter water quality analyzer is provided with the rechargeable battery, thus being capable of working normally without external power source; therefore, the analyzer can be applied to remote water quality detection sites conveniently.

Description

technical field [0001] The invention belongs to the technical field of water quality analysis, and in particular relates to a multi-parameter water quality analyzer. Background technique [0002] Human beings cannot live without water, and the quality of drinking water is closely related to human health. With the development of society and economy, the progress of science and the improvement of people's living standards, people's requirements for the quality of drinking water have been continuously improved, and the standards for drinking water quality have also been continuously developed and improved accordingly. Since the establishment of drinking water quality standards is related to many factors such as people's living habits, culture, economic conditions, scientific and technological development level, water resources and their water quality status, not only between countries, but also between different regions of the same country, There are differences in the require...

Problems solved by technology

[0006] Most of the existing water quality analyzers detect various ions in the water, analyze the concentration of various ions in the water quality, and obtain the water quality situation, but the parameters analyzed by the existing water quality analyzers are limited and cannot be comprehensively analyzed. It is impossible to effectively determine the water quality by testing the water quality, such as: dissolved oxygen, PH, ORP (oxidation-reduction potential), conductivity (salinity, resistance), temperature and other parameters, which cannot be fully tested.
