Holding the thermometer by its bulb can transfer heat from your hand to the bulb, affecting the temperature reading. This can lead to inaccurate results. It's best to hold the thermometer at the opposite end to prevent any interference with the measurement.

Holding the thermometer by its bulb can transfer heat from your hand to the bulb, affecting the temperature reading and providing inaccurate results. It's recommended to hold the thermometer by the stem to prevent any external heat sources from interfering with the measurement.
A psychrometer has two thermometers: a wet bulb thermometer and a dry bulb thermometer. It is used to measure relative humidity and can also determine dew point.
A dry bulb thermometer is an ordinary one. It's given this name when it's used to measure air temperature. A wet bulb thermometer takes into account humidity.
A sling psychrometer typically contains two thermometers: a dry bulb thermometer and a wet bulb thermometer. The dry bulb thermometer measures the air temperature, while the wet bulb thermometer measures the wet bulb temperature after being moistened with water. These readings are used to calculate the relative humidity of the air.
The best is a thermometer, another way to get the temperature outside is to pour water in a bowl, leave it out there for a couple of minutes and then take a thermometer and put it in the water.
To find the relative humidity using a wet-bulb thermometer and a dry-bulb thermometer, first measure the air temperature with the dry-bulb thermometer. Then, moisten the wick of the wet-bulb thermometer and expose it to airflow while taking the temperature reading. The difference between the dry-bulb and wet-bulb temperatures can be used with a psychrometric chart or formula to calculate the relative humidity of the air. This process works because the wet-bulb thermometer cools down through evaporation, and the greater the difference between the two temperatures, the lower the relative humidity.
The wet bulb thermometer is typically read lower than the dry bulb thermometer because the evaporation of water on the wet bulb cools the sensor by removing heat from it. This process is known as evaporative cooling and results in a lower temperature reading on the wet bulb thermometer compared to the dry bulb thermometer.
Yes as your fingers are warmer than the air surrounding the thermometer bulb.
