Part Number 139512

A single glass filter for checking the PFXi instruments in ASTM D1500 scale. This filter was supplied as part of the PFX195/2 accessories kit.

Conformance filters are assigned a nominal value and the company always endeavours to match this value as closely as possible. On occasion, because of the unique manner of the glass making process, it may not be possible to match the requested values exactly. The values achieved and the performance tolerances expected will, of course, always be reported.
