Key Features

Isokinetic sampling design

The inlet dimensions are matched to the required sample flow and downstream filter velocity to reduce size-dependent sampling errors.

Rectangular-to-round transition

A smooth internal transition supports particle transport from the rectangular scan inlet to the circular hose connection.

Precise edge and corner access

The probe geometry allows systematic scanning near filter frames, corners and sealing interfaces.

Efficient scanning width

The rectangular opening provides useful coverage transverse to the scan direction.

Consistent count response

Correct matching of inlet and downstream velocities supports location-independent particle-count results.

Optional protective cap

A cap and antistatic silicone hose are available for handling and connection to the particle counter.
