Problems solved by technology

Due to the deviation in the use of the concrete anti-seepage meter, it needs to be calibrated, but before the invention of the calibration device, there was no suitable calibration equipment for the comprehensive calibration of the concrete anti-seepage meter, and the concrete anti-seepage meter could not meet the traceability requirements of the value. Therefore, it is impossible to ensure that the value of the concrete impermeability meter is accurate and reliable

Description

technical field [0001] The invention relates to the technical field of measurement, in particular to a comprehensive calibration device for a concrete (mortar) anti-seepage instrument. Background technique [0002] Concrete impermeability meter is an instrument used to test the waterproof performance of concrete after hardening and determine its impermeability grade. It is an essential measuring instrument for concrete premixing enterprises and construction engineering quality inspection laboratories. Concrete impermeability instrument uses the principle that the pressure in the sealed container is equal everywhere, uses the water pump to supply the pressure to the whole system, and controls the pressurized pressure through the pressure instrument and the controller, so as to realize the water pressure from the bottom to the top. The test piece in the test mold, so as to measure the impermeability of the test piece and calculate its impermeability grade. Due to the deviatio...
