Abstract

The invention discloses a handheld water quality measuring instrument. The handheld water quality measuring instrument comprises a main controller connected with a working power supply, wherein the main controller comprises a single chip and a database module, which are connected with each other; the database module is connected with a communication protocol module used for communicating with a computer; the single chip is connected with a signal modulating module; and the signal modulating module is connected with a sensor module. The sensor module comprises an intelligent conductivity / salinity sensor, an intelligent oxidation-reduction potential sensor, an intelligent pH value sensor, an intelligent total dissolved gas sensor and an intelligent dissolved oxygen sensor. The handheld water quality measuring instrument disclosed by the invention has the advantages of high measuring accuracy, small volume and convenience for carrying and can be operated for a long time; and measuring water quality parameters can be simultaneously stored in the water quality measuring instrument and a personal computer.

Description

technical field [0001] The invention belongs to the technical field of water quality measuring instruments, in particular to a hand-held water quality measuring instrument. Background technique [0002] With the intensification of environmental pollution and the development of sewage treatment technology, water quality testing is becoming increasingly important in modern industrial and agricultural production. [0003] At present, the domestic research and development can be used in aquaculture, live fish transportation, soilless cultivation, greenhouse cultivation, sewage treatment fields, and can measure conductivity / salinity, redox potential, PH value, total dissolved gas (TGP), Dissolved oxygen (DO) measuring instruments have low accuracy and reliability; due to technology and cost control, the volume and weight of domestic water quality meters that can measure multiple parameters are too large, and the measurement data cannot be stored in the water quality measuring ins...
