The viewing tube insert shortens the optical path length. Reducing the path length allows more concentrated samples, to be viewed within a usable visual range. This reduction in path length extends the measurable concentration range of the method.

The insert is specifically for use in the following kits: CN-80 (Chlorine Free and Total); HS-WR (Sulfide); IR-10 (Iron) and OS-1 (Oxygen Scavengers).
