Function of Medical Mask Differential Pressure Tester

Medical Mask Differential Pressure Tester is a specialized instrument used to detect the breathability performance (i.e., pressure difference) of medical face masks. The Medical Mask Differential Pressure Tester assesses the breathability of masks by simulating artificial respiration and generating a pressure difference across the mask using a specific airflow rate. This instrument primarily consists of an adjustable flow air source, a sample clamping device, a differential pressure sensor, a flow sensor, and a control system. During the testing process, the instrument can precisely control the airflow rate and measure and record the pressure difference data across the mask in real time.

Qinsun Instruments Co., LTD, established in 2012, focuses on the research and development, design, and production of textile testing instruments. It provides textile testing instruments and services to academic research units and testing institutions. Qinsun is currently one of the most competitive and R&D-capable manufacturers of textile testing instruments in China, with an R&D team composed of experienced engineers. We are dedicated to serving our customers with all our hearts and striving to promote technological innovation in textile testing instruments.

Features

• High-Precision Measurement: The Medical Mask Differential Pressure Tester employs high-precision differential pressure sensors and flow meters to accurately measure the pressure difference and gas flow across the mask, ensuring the accuracy of test results.
• Versatility: This instrument is not only suitable for testing the breathability of medical masks but can also be used for testing other types of masks and textile materials. Additionally, it supports multiple testing modes and parameter settings to meet the testing needs of different mask products.
• Automation and Intelligence: Medical Mask Differential Pressure Testers typically adopt automated operational procedures, such as automatic calibration and testing, reducing errors caused by manual operations. Some instruments are also equipped with intelligent control systems that can automatically adjust testing parameters based on preset conditions and provide real-time test result feedback.
• Ease of Operation: The instrument features a user-friendly interface that is easy to learn. Users can complete the test by following simple setup and operational prompts.
• Data Recording and Report Generation: The Medical Mask Differential Pressure Tester can record test data in real time and automatically generate test reports upon completion. This provides users with convenient data management and analysis tools.

Applicable Standards

Functional Description

• Test Preparation: Users need to mount the mask sample to be tested onto a channel (clamp) with a fixed cross-sectional area and ensure good sealing between the sample and the clamp. Next, connect the air source to the instrument and set appropriate test parameters, such as airflow rate and test duration.
• Test Execution: After initiating the test program, the instrument will automatically control the airflow rate and generate a certain pressure difference across the mask. Simultaneously, the instrument will measure and record pressure difference data and gas flow data in real time.
• Result Judgment: Upon completion of the test, the instrument will automatically judge the test results and display pass/fail information based on preset standards. Users can also view detailed test data and reports for subsequent analysis and processing.
• Safety Protection: The Medical Mask Differential Pressure Tester fully considers safety protection measures in its design and use. For example, the instrument is equipped with overload protection devices and alarm systems that can promptly shut down and issue alerts in case of abnormalities, ensuring user safety.
