AHC-7L Direct Reading Concrete Air Entrainment Meter Test Equipment
This instrument is used to measure the air content in concrete by air pressure method. It can be divided into two ways: water injection and no water injection. The operation is simple and the gas content can be read out accurately from the dial. Read the black scale for water injection measurement, and read the red scale for no water injection measurement.
