Abstract

The invention provides a method for evaluating the stability of an ocean electrode type conductivity sensor. The method comprises the following steps of: S1, preparing before an experiment, cleaning a sacrificial anode, a conductivity sensor and related instruments, and adjusting an experimental environment to ensure the accuracy of an experimental result; S2, testing conductivity values measured by the conductivity sensor at different temperatures by changing the temperature; S3, placing all seawater samples and a laboratory salinity meter in a salinity measurement laboratory, placing the seawater samples and the laboratory salinity meter at a constant temperature for a period of time, measuring the standard salinity of the seawater samples, calculating the standard salinity value, and calculating the standard conductivity value according to the standard temperature value; and S4, calculating the conductivity stability of the conductivity sensor according to the conductivity value measured by the conductivity sensor and the standard conductivity value. According to the evaluation method, the stability index of the ocean electrode type conductivity sensor can be reasonably, truly and effectively evaluated, and the industry blank of the method is filled.

Description

technical field [0001] The invention belongs to the technical field of stability assessment of a marine electrode-type conductivity sensor, and in particular relates to a method for evaluating the stability of a marine electrode-type conductivity sensor. Background technique [0002] In the field of marine research, seawater density is a basic ocean hydrological element and one of the most important observation items in marine surveys and monitoring of marine environmental pollution. The seawater density measurement is calculated by measuring the relative salinity of seawater, while the relative salinity of seawater is calculated by the measurement of electrical conductivity. Therefore, the conductivity sensor should have the advantages of high accuracy, good stability, and short response time. In the "JJG763-2019 Verification Regulations for Temperature, Salt and Depth Measuring Instruments" implemented at this stage, there is a clear evaluation method for the accuracy of t...
