Medical mask gas exchange pressure difference tester Medical Face Masks Differential Pressure Tester

Model: RF4308AP

Medical mask gas exchange pressure difference tester is an instrument used to test the breathability (pressure difference) of medical masks.

Install the mask sample on a channel (fixture) with a fixed cross-sectional area, start the vacuum pump, and the air flow of a specific flow rate will produce a certain pressure difference between the upper and lower sides of the test sample, thereby calculating the ventilation performance of the mask.

RF4308AP tester, built-in precision air pump, flow sensor, differential pressure sensor, single-chip control, precise control of flow rate and differential pressure measurement.
