AWISEL
Photometers
For filter integrity and particle-based verification measurements.
Filter integrity
Particle-based filter testing, matched to method and reporting.
Photometers support HEPA and ULPA leak testing workflows where upstream challenge concentration and downstream readings need to be clear, repeatable and reportable.
AWISEL reviews photometer selection, probe configuration, reporting expectations and user training together with the test method, room type and applicable procedure.
Photometer options
ATI 2i Aerosol Photometer.
This page presents the ATI 2i family for HEPA and ULPA filter leak testing. AWISEL reviews instrument, probe, accessory, reporting and training needs as one selection path.
2i ecosystem
One photometer, clearer configuration choices.
Portable aerosol photometer for HEPA / ULPA leak scan work, with USB output and optional thermal printer support.
Scanning probe with 4.3-inch color touchscreen, scan records and upstream / downstream / clear valve control from the probe.
Sealed sample train configuration for projects that need ASME N511, ASME 510, ASME 509 or ASME AG-1 compatibility.
