- The instrument measures the wet compressive strength with a pressure sensor and measures the gas permeability using a barometric pressure sensor.
- All actions are driven by air pressure.
- The acquisition, processing, calculation and final printing of the detection signals are automatically performed under the control of the microcomputer.
- The instrument is simple in structure, easy to operate, and fast and accurate.
Description
- 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.
- It is used to determine the air permeability of moulding sand and core sand in dry or wet condition.
