Product Details

The TSI Mask Integrity Test Accessory (MITA) 8120 works in tandem with the CBRN Mask Protection Assessment Test System or PortaCount® Respirator Fit Tester to quickly detect leaks in CBRN gas masks and commercial respirators and ensure your personnel are getting maximum protection. 

MITA assesses the overall integrity of masks by performing an aerosol leak test utilizing the PortaCount Respirator Fit Tester as a particle detector. While under conditions of negative pressure and constant flow, the mask is tested on a full headform with an enhanced bladder seal system to provide a tight seal for most CBRN gas mask and commercial respirator types and sizes. Testing masks on MITA’s full headform configuration allows for use of the mask’s head harness, mimicking a real-life application and providing more accurate test results. 

If a leak is detected during the assessment, the integrated aerosol wand and the generator are used to pinpoint invisible leaks for quick evaluation and repair. The operator uses the aerosol wand to direct a stream of concentrated particles at specific locations around the mask until the single-particle counting capability of the PortaCount Respirator Fit Tester detects the suddenly elevated particle concentration and alerts the operator. 


  • Separate tests for overall mask integrity (Protection Factor), exhalation valve and drink tube
  • Integrated aerosol wand pinpoints leak locations, allowing for immediate evaluation and repair
  • Full headform configuration allows for use of the mask’s head harness, mimicking real-life application and providing more accurate test results. 
  • Single head form with an enhanced bladder seal system creates a tight seal for most gas mask and full face respirator types and sizes.
  • Easy-to-read display with an intuitive step-by-step test sequence allows for minimal operator training
  • Streamlined menu structure and no-nonsense keypad eliminate redundant button pushing
  • Quick setup/teardown process saves time
  • Efficient test sequence allows for 12+ mask assessments per hour
  • Packaged for ease of transport with one carrying case for the instrument and all components

  • What are the size-fraction definitions for health-related sampling?
    The health affects of particles are dependent on where they deposit in the respiratory tract. Particles that can be breathed into the nose or mouth by normal adults are called inhalable. Smaller particles that penetrate into the respiratory tract below the larynx are called thoracic. The smallest particles, the ones that are breathed deep into the alveolar region of the lung, are called respirable.
  • What do inspirable, inhalable and total particles mean?
    The terms "inspirable" and "inhalable" mean the same thing and can be used interchangeably to represent the particles that enter the nose and mouth. The commonly accepted term by the ACGIH/CEN/ISO committees is "inhalable". "Total" particles refer to all particles that are suspended in the air, whether they can be breathed in or not. "Total" usually implies that no inlet conditioning devices have been used to classify the sample.
