The product conforms to jjg577-2012 membrane gas meter verification regulation, and implements enterprise standard Q / wth25-2016: th-j series pressure flow calibrator.
Th-j3 flow calibrator is a device developed to meet the calibration requirements of dust and dust samplers used in environmental detection. After calibration by the measurement department, the accuracy and consistency of the measurement value transmission can be ensured. It can be widely used in the field calibration of other instruments and meters with the same parameter dose range used in environmental detection, so as to ensure the measurement accuracy of the calibrated instruments and the comparability of the use results. It is stipulated that the sampling instrument should be calibrated periodically in use. This device is an ideal device to complete this work.
