Sensitive Media

Replacing the inspection window

For light-sensitive media (e.g., iodine, potassium permanganate and
silver nitrate solutions), we recommend the use of the colored light
shield inspection window.
1.
Unscrew the air vent cap by hand or use a coin (Fig. 1).
2.
Remove the rear housing (Fig. 2).
3.
Unclip the rear inspection window on one side and pull it out
(Fig. 3).
4.
Place the colored inspection window with the slight curvature into
the rear housing.
5.
To change the front inspection window, lift up one corner of the
window, e.g., with a fingernail, and pull it out (Fig. 5).
6.
Place the colored inspection window with the larger curvature in
the front casing.
7.
First connect the housing at the top, then snap it closed.
Screw in the air vent cap.
Mounting a drying tube (optional)
Use of a drying tube might be necessary for moisture-sensitive media (see 'Accessories', page 62).
1.
Unscrew the air vent cap (see above).
2.
Fill the drying tube with a suitable absorbent (purchased sepa-
rately), and mount this in place of the air vent cap.
Note:
If necessary, seal the threads of the drying tube, the bottle and/
or the thread adapter with PTFE tape.
