Key Features
- Pair of thermometers to measure the relative humidity of the atmosphere
- One thermometer has a wet bulb, the other is kept dry
- Water evaporating from the wet bulb lowers its temperature
- The difference between the readings depicts the relative humidity
About This Product
A wet and dry bulb pair works because water evaporating from the wet bulb takes heat from it, so the wet bulb reads lower than the dry bulb. The drier the air, the faster the evaporation and the larger the difference between the two readings. That difference is used to find the relative humidity, often with a humidity chart. The pair is used in physics, air conditioning and meteorology lessons.
Frequently Asked Questions
Q1. What do the Wet and Dry Thermometers measure?
They measure the relative humidity in the atmosphere.
Q2. How does the pair work?
One thermometer has a wet bulb and the other is kept dry. When water evaporates from the wet bulb its temperature falls, and the difference between the readings depicts the relative humidity.
