T431N Mask & Respirator Breathing Resistance Tester

T431 Respirator breathing resistance tester is professional designed for determining the protective mask respiratory breathability resistance performance. By providing certain air flow according to the standard, the measured pressures for inhalation and exhalation can be used to determine the breathe resistance of tested protective mask. The respirator breathe resistance test apparatus can also be used to test leakage and air tightness property with accessories.

Artificial lung can simulate the different breathing conditions for dynamic test and provide pass or not by analyzing test results. Breathing resistance curve and testing data can be displayed on the computer and support printing or storage in the computer for further use.
