Test samples can be cold air test temperature close to the actual temperature of heat load to the main part, simulation users actually use refillable pressure for quick testing.
You can sample the test pneumatic test cold, the heating load can also be connected to the main component temperature close to the actual temperature, refillable simulate the working pressure of the user's actual use, rapid test.
Test samples can be cold air inflation test, but also can be heated to the main parts of the load temperature close to the actual temperature, and then inflated to simulate the user's actual work pressure, rapid test.
