Research on Calibration of CD4 Multi-parameter Gas Detector for Mining

LIU Guo-qiang ZHU Lin-kai （Zunyi Product Quality Inspectionand Testing Institute）

Abstract：This paper conducts calibrationandresearch on theresultsofmulti-parameter gas detectors used in coal mines for methane，carbonmonoxide，oxygenand hydrogen sulfide gases，toensure thereliabilityof thecalibration resultsandthevalidityof the measurement results.Thecalibration is mainlybasedonthe verificationregulations of the four gases，and the calibration is carried out in accordance with the methods inthe gas regulations.The equipment used inthetestis theCD4 Multi-parameter Gas Detector producedby Henan Zhuoan Electronic Technology Co.，Ltd. This detector iscarried bythepersonnelinthemine，and itsreliabilityandstabilitycanbetter protectthesafetyof the personnel in the mine.According to the actualapplication scenarios of the detector in the mine，the experimentof the simultaneous introductionofthe four gases has beencarriedout，which is more in line with the actual useand can provide suggestions for future multi-scenario use.
