Abstract

The present invention relates to the field of calibration equipment of t environmental monitoring instruments, particularly to an in-situ knob type calibration apparatus. According to the present invention, the breakthrough innovation is achieved in the calibration methods, and the in-situ knob type calibration apparatus is used to overcome the problems in the prior art; the calibration apparatus is adopted as one part of the instrument, and rotates to achieve three working states such as working, part calibration and span calibration through the knob; and the in-situ knob type calibration apparatus is arranged in the instrument window lens, such that the in-situ knob type calibration apparatus is not affected by environmental pollution.

Description

technical field [0001] The invention relates to the field of calibrating instruments for environmental monitoring instruments, in particular to an in-situ knob type calibrating device. Background technique [0002] At present, the energy needed for my country's economic development mainly comes from coal combustion, and the particulate matter and sulfur dioxide released by coal combustion are the main pollutants that lead to the deterioration of the atmospheric environment. The particle concentration monitor is an essential instrument in environmental monitoring, which can provide fast, reliable and accurate quantitative smoke and dust emission data to the environmental supervision department. According to the technical requirements HJ / T75-2007 and HJ / T76-2007 of the environmental protection department, in order to ensure the accuracy of the monitoring instrument itself, it is necessary to calibrate the instrument. [0003] Such as the published patent CN200820139944.7, the...
