A black bulb thermometer is a device used to measure the temperature of a surface by measuring the amount of thermal radiation it emits. It consists of a blackened bulb exposed to the surface being measured and a thermocouple or temperature sensor that registers the black bulb's temperature. This type of thermometer is commonly used in industrial settings to monitor the temperature of objects like ovens, furnaces, or heating systems.
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.
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 glass bulb of a thermometer is the part at the bottom of the thermometer that contains mercury or colored alcohol that expands and contracts with temperature changes. This expansion and contraction of the liquid is what causes the thermometer to measure and display the temperature.
The base of a thermometer is called the bulb. It is typically a small, glass reservoir at the bottom of the thermometer where the liquid or mercury expands and contracts with changes in temperature.
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 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.
When a dry bulb thermometer and a wet bulb thermometer read the same temperature, it indicates that the air is saturated with moisture and the relative humidity is 100%. This means that the air cannot hold any more moisture, resulting in no difference in temperature readings between the dry bulb and wet bulb thermometers.
