| 4C32.00 | Dew Point and Humidity | | |
| 4C32.10 | sling psychrometer | PIRA 1000 | |
| 4C32.10 | sling psychrometer | 4C32.10 | Use a commercial sling psychrometer to determine relative humidity. |
| 4C32.10 | sling psychrometer | Hl-2 | Two thermometers, one with a wet wick, are mounted on a device swung around the head. |
| 4C32.10 | sling psychrometer | M-22a.1 | Two thermometers, one with a wet wick on the bulb, are rotated. |
| 4C32.11 | wet and dry bulb thermometers | Hl-1 | Identical thermometers are mounted on a panel, one with a wet wick. |
| 4C32.11 | humidity | H-92 | Wet and Dry bulb readings. |
| 4C32.11 | wet and dry bulb | M-22a.2 | Wet and dry bulb thermometers are mounted on a frame with a humidity graph. |
| 4C32.15 | dial hygrometer | M-22a.3 | A dial type hygrometer is pictured. |
| 4C32.16 | demonstration hair hygrometer | Hl-3 | A hair is connected to a pivot. |
| 4C32.20 | dew point measurement | Hl-4 | Evaporating alcohol cools a shiny surface until dew forms. |
| 4C32.21 | dew point | Hl-5 | Evaporating ether cools a gold band until dew forms. |
| 4C32.22 | dew point | H-93 | Reflect a light beam off two bright plates, one cooled by ether. |
| 4C32.23 | dew point with evaporating ether | 27-3.10 | When the dew point is reached in a test tube of evaporating ether, water drops on the outside complete an electrical circuit, lighting a neon lamp. |
| 4C32.24 | condensation and coalescence | Hl-9 | Watch the shiny surface of a frigister as small water drops grow and coalesce. |
| 4C32.40 | condensation nuclei | PIRA 1000 | |
| 4C32.40 | condensation nuclei | Hl-6 | Cigar smoke is introduced into a steam jet. |
| 4C32.41 | condensation nuclei | Hl-7 | An extinguished match is held in the steam from a tea kettle. |
| 4C32.50 | fog in a bell jar | 27-3.11 | Place moistened cotton in a bell jar and evacuate until fog forms. After cleaning the air of dust, ions are introduced and a thick fog forms. |
