Abstract

The invention discloses a calibration method and a calibration system for a dust tester. The calibration system for the dust tester comprises a dust mixing device for obtaining mixed gas with uniform particle distribution, and a sampling calibration device for sampling the mixed gas to obtain first particle concentration and performing calculation processing according to the first particle concentration and second particle concentration which is obtained by detecting the mixed gas through the dust tester to be calibrated and is displayed by the dust tester to be calibrated to obtain a relative error of the dust tester to be calibrated. According to the calibration method and the calibration system for the dust tester, the accuracy and the traceability of the calibrated dust tester can be guaranteed.

Description

technical field

[0001] The invention relates to measurement technology, in particular to a method and system for calibrating a dust tester. Background technique

[0002] The dust tester is used to detect the concentration of particulate matter in the air environment. The accuracy and traceability of the dust tester have an important impact on the evaluation level of the air environment quality. The traceability can ensure that the measurement accuracy can be traced to the recognized measurement reference The source, that is, for the dust tester, means that the test data of the dust tester can be traced back to the most basic weighing method. Since the existing technology does not clearly stipulate how to verify and calibrate the dust tester, it is difficult for the dust tester to achieve accurate value traceability. Therefore, in order to strengthen the accuracy and traceability of the dust tester, it is necessary A dust tester calibration system is provided to calibrate an...
