Product Introduction：

PortaCount Mask Integrity Testing System ™ The respirator 8048 and mask protection evaluation testing system can quickly detect leaks from gas masks and commercial respirators, ensuring maximum personnel safety. MITA uses a respirator suitability tester as a particle detector for aerosol leak testing to evaluate the integrity of the mask. Under negative pressure and constant current conditions, the mask was tested on a full head mold equipped with an enhanced bag sealing system, which can provide complete sealing for most types and sizes of gas masks and full face respirators. The full head model configuration allows the use of face masks and headbands, which can simulate practical applications in real life and provide more accurate measurement results.

When leaks are found during the evaluation process, integrated aerosol probes and generators can be used to determine the location of the leak for rapid diagnosis and repair. The operator uses an aerosol probe to indicate the specific location of particle aggregation around the mask, and the single particle counting ability of the respirator suitability tester can detect sudden increases in particle concentration and sound an alarm.

原理：

‌面罩完整性测试仪和面罩完整性测试系统的原理主要基于压力变化和气体流动的检测‌。

在测试过程中，系统首先向面罩内部充入一定的气体（通常是空气或其他惰性气体）。随后，系统开始监测气体在面罩内部的压力变化。通过高精度传感器，系统可以实时监测气体是否通过面罩的接触点泄漏，并记录下的泄漏量和压力变化情况作为测试结果。这种原理确保了能够准确评估面罩的密封性能和结构完整性。‌

Principle:

The principle of the mask integrity tester and mask integrity testing system is mainly based on the detection of pressure changes and gas flow.

During the testing process, the system first fills the inside of the mask with a certain amount of gas (usually air or other inert gas). Subsequently, the system began monitoring the pressure changes of the gas inside the mask. Through high-precision sensors, the system can monitor in real-time whether gas leaks through the contact points of the mask, and record the amount of leakage and pressure changes as test results. This principle ensures accurate evaluation of the sealing performance and structural integrity of the face mask.

应用领域：

‌面罩完整性测试仪和面罩完整性测试系统主要应用于医疗、化工、消防等领域‌。

在医疗领域，面罩完整性测试仪被广泛应用于呼吸治疗、外科手术及急救等场合。在无创通气、氧气疗法中，确保面罩的密封性对于维持有效通气至关重要，测试仪能够定期检测面罩性能，预防因泄漏导致的治疗失败‌1。

在化工领域，面罩完整性测试系统用于检测防毒面具、呼吸器等防护装备的完整性和泄露情况，确保工作人员在有害气体环境中得到充分的保护‌。

此外，在消防领域，面罩完整性测试仪和测试系统也发挥着重要作用，帮助消防员在紧急情况下确保呼吸面罩的密封性和完整性，从而保障他们的生命安全。‌

Application Areas:

The mask integrity tester and mask integrity testing system are mainly used in medical, chemical, fire and other fields.

In the medical field, mask integrity testers are widely used in respiratory therapy, surgical procedures, and emergency situations. In non-invasive ventilation and oxygen therapy, ensuring the sealing of the mask is crucial for maintaining effective ventilation. The tester can regularly test the performance of the mask to prevent treatment failure caused by leaks.

In the field of chemical engineering, mask integrity testing systems are used to detect the integrity and leakage of protective equipment such as gas masks and respirators, ensuring that workers are adequately protected in hazardous gas environments.

In addition, in the field of firefighting, mask integrity testers and testing systems also play an important role in helping firefighters ensure the sealing and integrity of breathing masks in emergency situations, thereby safeguarding their lives.
