The Qinsun PortaCount Respirator Fit Tester assesses the overall integrity of masks by performing an aerosol leak test using the PortaCount particle detector. The instrument operates under controlled negative pressure and constant airflow, providing accurate quantitative fit measurements. Masks are tested on a full headform with an enhanced bladder seal system to simulate real-life usage, allowing the mask’s head harness to function naturally and ensuring more precise test results.This system eliminates the guesswork and variability of qualitative fit tests, providing objective and repeatable evaluation of mask fit and protection performance.
Application
The PortaCount Respirator Fit Tester is suitable for fit and integrity testing across the following industries and products:
(1) Military and Defense: CBRN gas masks, full-face respirators — overall fit and protection factor assessment
(2) Occupational Safety: commercial respirators, industrial dust masks, half-face and full-face respirators — fit testing and leak detection
(3) Medical and Healthcare Industry: surgical masks, N95/FFP masks, medical respirators — quantitative fit evaluation
(4) Research and Development: development of new respirator models and harness designs, optimization of fit and seal
(5) Quality Control: production batch verification, ensuring proper mask fit for various models and sizes
(6) Third-Party Testing Laboratories: certification testing, evaluation of mask protection factor, exhalation valve and drink tube performance
The instrument is widely used for product development, R&D, production quality control, and laboratory fit testing.
Standards
The instrument complies with and can be applied to the following standards (including but not limited to):
(1) ISO 16975-3:2017 – Respiratory Protective Devices — Selection, Use, and Maintenance — Part 3: Fit Testing Procedures
Features
(1) Separate testing for overall mask integrity (Protection Factor), exhalation valve, and drink tube
(2) Integrated aerosol wand for pinpointing leak locations, enabling immediate evaluation and repair
(3) Full headform configuration allows the mask’s head harness to function naturally, simulating real-life use
(4) Single headform with enhanced bladder seal system provides a tight seal for most gas mask and full-face respirator types and sizes
(5) Easy-to-read display and intuitive step-by-step test sequence minimize operator training requirements
(6) Objective quantitative measurement eliminates the uncertainty of qualitative fit testing
