Product Introduction

This HEPA filter integrity tester combines a regulated photometric measurement module, selectable upstream and downstream sampling paths, and guided leak-test software in one field-ready enclosure. The operator establishes the upstream challenge baseline, scans the downstream filter face and records localized penetration against the configured alarm threshold. A color interface, probe connection and exportable test records support repeatable qualification of cleanroom terminal filters, containment cabinets and air-handling filter banks.

Key Features

Integrated photometric detection reports aerosol penetration during live filter scans.

Guided upstream baseline, clear-air zero and downstream scan modes reduce sequence errors.

Regulated sampling flow maintains consistent response at the scanning probe.

Configurable alarm thresholds highlight leaks at media, frame and seal locations.

Onboard records associate scan results with filter and room identifiers.

Rugged portable housing supports qualification work across controlled facilities.

Customer Product Concerns

A defensible integrity test requires a stable challenge baseline, controlled probe sampling and reliable association between every scan and its filter location.

Operators may perform zeroing, baseline measurement and scanning in the wrong order.A guided workflow presents each sampling mode in sequence and confirms readiness before scanning.

A fluctuating upstream challenge can make penetration results difficult to interpret.Baseline monitoring and clear status indication reveal concentration changes before they compromise the scan.

Small local leaks can be overlooked during a large filter survey.Immediate visual and audible alarms mark threshold excursions while peak response is retained.

Manual notes can separate test results from the correct filter location.Structured filter, room and operator fields keep each saved scan associated with its test point.
