Upgrading of Mining High and Low Concentration Methane Sensor Calibration Device
In recent years,with the succession of high gas mines,mining of high gas seams,the application of large mining height technology and the comprehensive coverage of safety equipment,the catalytic combustion type low concentration methane sensors and portable methane determiners originally installed and operated can no longer meet the requirements of the construction,and the amount of high and low concentration methane sensors needing to be rotated has increased greatly.The existing DCKJ-1 type high and low concentration methane sensor calibration device calibration samples are limited,after the transformation to increase the suspension device,voltage regulator power supply,distribution board and wiring cable,can multiply the number of instrument calibration.
