Introducción del producto

This aerosol photometer draws a controlled sample through a light-scattering chamber and reports challenge concentration or filter penetration in real time. Dedicated upstream, downstream and clear-flow connections support the complete integrity-test sequence, while a color interface presents the baseline, alarm threshold and live scan response. The rugged portable enclosure accommodates field validation work in cleanrooms, laboratories and containment facilities.

Características clave

Forward light scattering provides continuous response across filter scan locations.

Automatic zero and upstream normalization reduce setup steps before scanning.

Regulated sample flow supports repeatable probe response and leak localization.

Selectable audible and visual alarms alert the operator at the chosen threshold.

Dedicated upstream, downstream and clear ports organize the sampling sequence.

Portable enclosure and probe interface support room-to-room validation work.

Preocupaciones del producto del cliente

A dependable integrity scan requires stable sample flow, a clean zero reference and immediate indication of localized aerosol penetration.

Unstable sample flow can change response while the probe crosses the filter face.Closed-loop flow regulation maintains a defined sampling rate through the optical chamber.

Residual aerosol can delay zeroing between upstream and downstream measurements.A dedicated clear-air path purges the sample train and establishes the zero baseline.

Small penetration peaks may be missed during a long manual scan.A configurable alarm and peak indication draw attention to threshold excursions in real time.

Incorrect reagent response can bias concentration readings.Selectable response settings accommodate common PAO, DEHS, DOP and paraffin challenge liquids.
