Wet and Dry Bulb Water Bath

The wick should be changed frequently, the period between changes depending on the surrounding atmosphere.

In wood drying kilns, etc., the wick should be renewed once a week but in clean atmospheres, e.g. offices, it can

be left as long as three weeks. The water must be kept clean and free from impurities.
