Data Calculation and Interpretation Once you have the temperature readings, you can calculate the relative humidity using a psychrometric chart or an online calculator. By inputting the dry-bulb and wet-bulb temperatures, the device provides the relative humidity percentage, indicating how much moisture the air is holding compared to its maximum capacity at that temperature.
After swinging, immediately read the temperatures from both thermometers. Use distilled water to avoid impurities that could affect the accuracy of the reading.
How to Use a Psychrometer and Avoid Impurities with Distilled Water
This device typically consists of two thermometers, one dry and one wet, which work together to calculate the dew point and relative humidity of the surrounding environment. Environmental conditions also play a significant role in the accuracy of your measurements.
