RH-TQZ500 Melt Spraying Cloth Breathability Tester/Computer Air permeability tester ISO296
Resistance testing principle:
The pressure difference was calculated by adjusting the gas flow rate to 8L/min, and the result was reported as the pressure difference per square centimeter area.
RH-TQZ500 Melt Spraying Cloth Breathability Tester/Computer Air permeability tester ISO296
Testing principle:
Based on the principle design of differential pressure method, the preprocessed sample is placed between the upper and lower measuring surfaces, and a constant differential pressure is formed on both sides of the sample. Under the effect of differential pressure, the gas flows from the high-pressure side to the low-pressure side through the sample. The permeability of the sample is calculated according to the area, differential pressure and flow through the sample.Or a constant airflow is formed on both sides of the sample, the pressure difference between the two sides of the sample is recorded, and the permeability of the sample is calculated.
Product features
The instrument chip and sensor are imported from the United States, the test results are accurate, good repeatability, high precision.
The calibration of pressure sensor and flow sensor is traceable.
Exquisite design: the instrument USES microcomputer technology, the test process is completely automated, fast and accurate.Touch screen LCD display results, and with data recording and processing functions, with printout.
(3) superior performance: compared with the traditional breathability meter, this instrument has a very high advantage, the low breathability of the paper, can be set higher pressure difference, and the high breathability of the paper can be set lower pressure difference, easy and accurate determination of the results.
Easy to use, high automation: the traditional breathability tester test is not only slow and laborious, on the contrary, the breathability tester test is automatic and fast, at the same time the accuracy of the test results has been guaranteed.Misoperation or low reproducibility of test results, which are caused by poor instrument design and manufacturing techniques, are effectively avoided in this instrument.
