Aerosol Photometer for HEPA Filter Testing
Select a HEPA leak-test photometer by method, aerosol, dynamic range, probe workflow, data integrity, report output and service—not by instrument price alone.
The purchasing failure to avoid
A photometer can meet its bench specification and still fail the field workflow if the upstream challenge, probe, tubing, valve control, report format or generator pairing is wrong.
Minimum technical requirement
| Governing method | Facility procedure, applicable standard, aerosol type, acceptance threshold and upstream challenge range. |
|---|---|
| Instrument and probe | Dynamic range, response, zero/reference workflow, scanning probe, cable length, controls and ergonomics. |
| Data integrity | Storage, user access, auditability, report export, timestamps and traceability. |
| Accessories | Cases, tubing, printer, adapters, spare filters, probe heads and verification tools. |
| Calibration/service | Calibration scope, uncertainty, turnaround, loaner strategy and technician training. |
