Product Overview
The HM-AP1 from HM Instruments is an aerosol photometer based on Mie light scattering. It measures aerosol concentration and displays leakage-related data during on-site integrity testing of high-efficiency filter systems.
Key Features
- A solid-state LED source and photomultiplier detection support aerosol measurement.
- The 7-inch LCD and portable scanning probe display measurement and instrument status.
- Audible and visual alarms indicate a selected concentration threshold.
- Stored measurement data can be printed or exported through USB storage.
- Automatic zero establishment is performed at startup.
Applications
Use for leak testing of HEPA filters, HVAC filter systems, biological safety cabinets, cleanrooms and gloveboxes with an appropriate challenge aerosol. Select PAO, DOP or another supported aerosol medium for the test procedure.
