[0002] With the development of society and the progress of science, higher requirements are put forward for various materials, and the same applies to the instruments for testing the performance of materials.

[0003] The corresponding national standards for existing testing instruments require that the same specification specimens be tested at least three times under the same experimental environment for comparison, and the comparison of the results of these three experiments is used to judge the credibility and authenticity of the experimental results. Due to the instrument structure problem, only one specimen can be tested at a time, and the same specification of test samples need to be tested multiple times in the same experimental environment. Such multiple experiments not only waste resources and time, but also it is difficult to ensure that the specifications and environments are necessarily the same each time, and there is a possibility of error. Once the error is too large, more resources and time will inevitably be wasted, resulting in an increase in experimental costs. Content of the Utility Model

[0044] Working principle:

[0045] When the device is in use, first rotate the fastening bolts A 22, fastening bolts B 35, and fastening bolts C 48 to loosen and remove the fixed clamping mechanisms A 21, clamping mechanism B 34, and clamping mechanism C 47. Then remove the test top cavity A 23, test top cavity B 36, and test top cavity C 49. Place the test sample A 14 into the test inner cavity A 15, the test sample B 27 into the test inner cavity B 28, and the test sample C 40 into the test inner cavity C 41. Then put the removed test top cavity A 23, test top cavity B 36, and test top cavity C 49 back, re-fix and connect the clamping mechanisms A 21, clamping mechanism B 34, and clamping mechanism C 47, and re-rotate the fastening bolts A 22, fastening bolts B 35, and fastening bolts C 48.

[0046] Through the control device, start the humidifier 51 and the heating sheet 50, and control the rise and fall of temperature and humidity according to the actual test requirements. The water vapor generated by the humidifier 51 enters the air inlet 7 along the humidifier trachea 52, and enters the four-way ventilation device 10 along the air inlet connection disk 9. The air inlet sealing ring 8 can ensure that the water vapor does not leak out.

[0047] The water vapor entering the four-way ventilation device 10 enters the respective corresponding tracheas through the nozzle A 12, nozzle B 25, nozzle C 38, and nozzle D 54. The water vapor of the nozzle A 12 enters the trachea A 11, the water vapor of the nozzle B 25 enters the trachea B 24, the water vapor of the nozzle C 38 enters the trachea C 37, and the nozzle D 54 enters the trachea D 53.

[0048] The water vapor entering the trachea D 53 is sent into the main cavity seat through the connection port D 55, so that the water vapor flows between the main cavity seat and the test sample A 14, test sample B 27, and test sample C 40.

[0049] The water vapor entering the trachea A 11 enters the test inner cavity A 15 in the test top cavity A 23 through the connection port A 13 and starts to contact the test sample A 14. The probe A 19 of the weighing sensor A 18 at the other port of the test sample A 14 then starts to record relevant data. The weighing sensor A 18 judges and calculates the corresponding transmittance and permeation amount by measuring the content of the test lower cavity marker to obtain the experimental results required for the test top cavity A 23.

[0050] The water vapor entering the trachea B24 enters the test inner cavity B28 in the test top cavity B36 through the connection port B26 and starts to contact the test sample B27. The probe B32 of the weighing sensor B31 located at the other port of the test sample B27 then starts to record relevant data. The weighing sensor B31 determines and calculates the corresponding transmittance and permeation amount by testing the content of the marker in the test lower cavity to obtain the experimental results required for the test top cavity B36.

[0051] The water vapor entering the trachea C37 enters the test inner cavity C41 in the test top cavity C49 through the connection port C and starts to contact the test sample C40. The probe C45 of the weighing sensor C44 located at the other port of the test sample C40 then starts to record relevant data. The weighing sensor C44 determines and calculates the corresponding transmittance and permeation amount by testing the content of the marker in the test lower cavity to obtain the experimental results required for the test top cavity C49.

[0052] After the test is completed, the control device stops the water vapor input of the humidifier 51 and the heating of the heating sheet 50. After waiting for the main body cavity seat 1, the temperature control cavity, the test top cavity A23, the test top cavity B36, and the test top cavity C49 to return to normal, rotate the fastening bolts A22, the fastening bolt B35, and the fastening bolt C48 to loosen and remove the fixed clamping mechanisms A21, the clamping mechanism B34, and the clamping mechanism C47. Then remove the test top cavity A23, the test top cavity B36, and the test top cavity C49, take out the test samples A14, the test sample B27, and the test sample C40, put back the test inner cavities A15, the test inner cavity B28, and the test inner cavity C41, fixedly connect the clamping mechanisms A21, the clamping mechanism B34, and the clamping mechanism C47, and rotate and fasten the fastening bolts A22, the fastening bolt B35, and the fastening bolt C48 to end the experiment.
