To solve the problem of multi-parameter calibration of concrete impermeability meter,a calibration de-vice is developed to detect the error of pressure indication value and set pressure holding error in the field.The im-permeability meter and standard are connected by stainless steel sealed disc,and the measurement is carried out through the pump pressure boost of the impermeability meter.The results show that the device has the ability of data recording and analysis,and can automatically generate the original record according to the experimental data,which meets the requirements of the standard of JJF 1812-2020"Calibration Specification of Concrete Impermea-bility Meter"and JG/T 249-2009"Concrete impermeability Meter",and can improve the detection efficiency and accuracy.
