Product Description

RT-2516 Mask pressure difference tester is test air permeability of mask, measured by determining the difference of pressure across the mask under specific conditions of air flow, temperature and humidity.

RT-2516 Mask pressure difference tester is appropriate for medical face masks intended to limit the transmission of infective agents from staff to patients during surgical procedures and other medical settings with similar requirements. A medical face mask with an appropriate microbial barrier can also be effective in reducing the emission of infective agents from the nose and mouth of an asymptomatic carrier or a patient with clinical symptoms.

Principle

RT-2516 Mask pressure difference tester measures the differential pressure required to draw air through a measured surface area at a constant air flow rate is used to measure the air exchange pressure of the medical face mask material, as shown in Figure C.1.

Water-filled manometers (M1 and M2) are used to measure the differential pressure. A flow meter is used for measurement of the airflow. An electric vacuum pump draws air through the apparatus and a needle valve is used to adjust the airflow rate.

RT-2516 Mask pressure difference tester is measured by gas pressure difference on both sides of the mask ( the damping from the mask exert to the airflow) to determine the breathability(differential pressure) of the mask.
