Description
1. Its main use is test the air permeability of moulding sand and
core sand in dry or wet condition.
2. It can be used for the direct measurement of the gas
permeability of castings in foundry, and also for the determination
of the permeability of
standard samples in the dry and wet state of foundry sand and
mixture.

Instrument features
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
5. Automatically switch the size of the orifice, without manual
intervention, the computer can only control the size of the hole
switch and closure,
to achieve full range of gas permeability automatic measurement.
6. Data storage and power-down protection function: It can store
100 sets of experimental results. In the event of power failure or
shutdown, the
collected data is completely saved in the computer system for
further display or printout.
7. Printing function: The dot matrix micro-printer can output the
collected and stored data. For two or more sets of data, the
average value can be
printed.
main applications
It is widely used in foundry, machinery, casting, qualitative
inspection, scientific research, university lab....
