It is used to determine the air permeability of moulding sand and core sand in dry or wet condition. It uses a special electronic frequency modulation motor, digitally controlled by a single chip microcomputer. High precision micro pressure sensor with constant air pressure output. It can automatically and accurately calculate the air permeability, display, data processing, storage and printing.
measuring range: -0981 Pa
