Abstract

The invention discloses a sea test method based on an ocean fixed platform and used for ocean water quality instruments. The method includes: inspecting a to-be-tested instrument; mounting and arranging the to-be-tested instrument; collecting and analyzing a water sample; processing data; analyzing the data. The method has the advantages that the method can provide detailed sea test steps of the ocean water quality measuring instruments, field water sampling data is used as the comparison data, the use controversy of standard instruments is avoided, the data is real and reliable, and a data analysis method with long-term stability and reliability is provided; the method improves part of the content of HY/T 141-2011 Specifications for Sea Test of Oceanographic Instruments which is exiting ocean industrial standards, and the sea test steps and data analysis method which are applicable to the research-stage measuring instruments for measuring ocean water quality factor such as pH, dissolved oxygen and turbidity are provided.

Description

technical field [0001] The present invention relates to a method for measuring marine instruments, in particular to a method for testing marine water quality (single parameter or combination) measuring instruments suitable for pH, dissolved oxygen (DO), and turbidity in the development stage. Background technique [0002] In recent years, my country's marine ecological environment monitoring technology has developed rapidly, forming a complete monitoring instrument system, and some instruments independently developed have begun to be applied. [0003] In terms of marine water quality monitoring, the National Marine Technology Center, Xiamen University and other units have developed measuring instruments for pH, dissolved oxygen, and turbidity. In the development stage of these instruments, indoor tests are mainly completed, including: according to GB / T 32065-2015 "Basic Environmental Test Methods for Marine Instruments (Parts 1 to 17)" and the abolished HY 016-1992 "Basic En...
