Abstract

Disclosed are a three-point flow type calibration device for a sodium ion concentration meter and a calibration method thereof. The device has the following characteristics: according to a sodium ionconcentration meter calibrate principle, three-point flow type calibration standard water samples are introduced, the samples are detected and jointly calculated by applying an Nernst equation, and sothe consistency of the flow state and flow rate of the to-be-measured water samples during measurement and a standard solution during calibration is ensured, the accuracy of calibration data is guaranteed, sodium ions brought into the whole process due to a plurality of reasons are solved, and the problem that two-point flow type calibration is inaccurate is solved. Meanwhile, the three-point flow type calibration device for a sodium ion concentration meter is developed and designed, which is suitable for requirements of the calibration method, gives full play to the calibration method, makeson-line and continuous monitoring of the water sample sodium ion concentration in the production process more accurate, and meets the needs of electric power, petrochemical and other fields.

Description

technical field [0001] The invention relates to a sodium ion concentration meter, in particular to a three-point flow calibration device and a calibration method for the sodium ion concentration meter. Background technique [0002] The sodium ion concentration meter is an online chemical analysis instrument, which is used in electric power, petrochemical and other fields. It mainly monitors the sodium ion concentration of boiler feed water, condensed water, saturated steam and superheated steam in power plants. It can continuously monitor the sodium ion content of water samples in the production process, which is suitable for the use environment of industrial sites and meets the actual needs of maintenance personnel. The sodium ion concentration meter must be calibrated before measuring the sodium ion concentration. If the sodium ion concentration meter is calibrated accurately, the measurement of the sodium ion concentration will be accurate. [0003] The sodium ion concen...
