Mask Tester

The Medical Face Mask Differential Pressure Tester, also known as the mask breathability tester, is an essential instrument designed to evaluate the breathability of medical face mask materials. This advanced device measures the differential pressure (Delta P) required to draw air through a specified surface area at a constant airflow rate, providing critical insights into the air exchange pressure of medical masks. By utilizing a suction air source, the tester operates independently of the testing site, making it versatile and user-friendly.

Equipped with a high-precision pressure difference sensor, the Medical Face Mask Differential Pressure Tester digitally displays the pressure difference on both sides of the sample, ensuring accurate and reliable results. The specially designed sample holder secures the mask material firmly in place during testing, allowing for consistent measurements. This device adheres to various industry standards, including YY 0469-2011. YY/T0969-2013. and EN 14683:2014 Annex C, as well as ASTM F2100. ensuring compliance with rigorous testing protocols.

With a flow meter range of 0 to 10 L/min and a manometer range of 0 to 1000 Pa with an accuracy of 1 Pa, this tester is capable of providing precise assessments of air permeability. The internal diameter of the top and bottom holders is 25 mm, and the test area measures 4.9 cm², making it suitable for a wide range of medical mask materials. The device operates on a power supply of 220 V, 50 Hz, and 200 W, and has a weight of 65 Kg, ensuring stability during operation.

In summary, the Medical Face Mask Differential Pressure Tester is a vital tool for manufacturers and quality control professionals in the medical industry, enabling them to ensure that their products meet the necessary safety and comfort standards. By accurately measuring the breathability of mask materials, this tester plays a crucial role in the production of effective and comfortable medical face masks.
