STD-Z intelligent digital display air permeability tester is the upgraded product of sand air permeability tester series. It is mainly used for the direct determination of the air permeability of the casting workshop, and also for the determination of the air permeability of the standard specimens of the raw sand and mixed materials for casting in the dry or wet state. It adopts the data acquisition and processing unit mainly composed of single reed chip and the micro-pressure measuring system composed of high performance diffusion silicon type pressure sensor with micro-printer, which has a breakthrough improvement in the accuracy of air permeability measurement and the reliability and stability of the instrument.
