Key Features

Isokinetic probe geometry

The rectangular inlet is matched to the particle-counter flow and filter downstream velocity to minimise sampling bias.

Smooth internal transition

The rectangular inlet transitions continuously to the round hose outlet, with a smooth internal surface to support particle transport.

Corner-access scanning

The probe shape supports precise scanning close to filter corners and frame interfaces.

Wide scanning footprint

The larger width transverse to the scan direction can reduce total scanning time.

Location-independent count response

Appropriate isokinetic sampling supports consistent count rates across the filter face.

Lightweight construction

Anodised-aluminium construction provides a low probe weight of approximately 0.17 kg.
