Instrument features
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.
1. It adopts electronic frequency modulation speed regulation
motor.
2. It is controlled by single chip micro computer.
3. It also adopts high precision micro pressure sensor in order to
supply constant air pressure output.
4. It can finish testing, data processing, displaying, data saving
and printing automaticly
main applications
It is widely used in foundry, machinery, casting, qualitative
inspection, scientific research, university lab....
