The Psychro-Dyne requires no whirling or special techniques and may operate in confined areas.

The operator is only required to wet te wick on the wet bulb, turn the instrument on, and allow the constant aspiration rate to cause the depression in wet bulb temperature. This operation, when compared to the conventional sling psychrometers, affords a safer, convenient, and more accurate method of RH determination. Night-time and dark space readings are provided by increasing the intensity of the illuminating thermometer scale. The high thermometers' breakage rate of the sling psychrometers is also eliminated in the Psychro-Dyne since the thermometers are shock mounted.
