Bacharach Replacement Wicks (4 Pack)

Sling Psychrometers are used to measure the air and wet bulb temperatures, in order to determine the relative humidity and dew point temperature.

This maintenance-free wall mount hygrometer equipped with a dual readout displays the temperature (0-160°F; -19.9-69.8°C) digitally and the humidity (20-100%) on an analog dial for simultaneous monitoring, in either °F or °C (switchable).
