01 / Application
Workflow and key features
The MHD-01A compares particle concentration inside and outside the worn facepiece under the defined exercise or test sequence. It converts a subjective fit check into a quantitative fit factor for respirator programs, product development and inspection.
- Quantitative fit result based on inside-to-outside particle concentration
- Supports masks, respirators and configured gas-mask facepieces
- Testing time can be adapted to the selected protocol
- Compatible aerosol sources include PSL, DEHS and DOP configurations
- Relevant to OSHA-oriented and GB 19083 mask-fit workflows
