The classical sling psychrometer has inherent errors in measuring the true thermodynamic wet bulb.
The classical sling psychrometer has inherent errors in measuring the true thermodynamic wet bulb. Velocity over the wet bulb is critical in this measurement, and therefore the twirling speeds of a sling psychrometer becomes critical in a true measurement.

When the operator stops twirling the sling psychrometer, the wet bulb depression immediately starts rising so that by the time he takes a reading, another error results. The portable psychrometer eliminates this error by a self-contained miniature fan drawing air over the wet bulb at the correct velocity. The readings are taken while the fan is still sampling the air. National Institute of Standards & Technology traceable thermometers assure accurate temperature readings.

All battery operated psychrometers include 3 ¡°D¡± cell batteries, water bottle, instruction manual, case and three month warranty on labor, one year parts
