Capillary Tube And Bulb Recording Thermometer

Capillary Tube and Bulb Recording Thermometer is a type of temperature measuring instrument that falls under the supply class Pressure, Temperature, and Humidity Measuring and Controlling Instruments in the supply group Instruments and Laboratory Equipment.

These thermometers consist of a glass bulb connected to a capillary tube. The bulb contains a liquid, usually mercury or alcohol, which expands or contracts with changes in temperature. The capillary tube is very narrow and acts as a conduit for the liquid to move up or down based on temperature fluctuations.

The capillary tube is typically marked with a scale that allows for temperature readings to be taken. The liquid in the bulb expands or contracts with temperature changes, causing the level of the liquid in the capillary tube to rise or fall accordingly. By observing the position of the liquid in the capillary tube, the temperature can be determined.

Capillary Tube and Bulb Recording Thermometers are commonly used in various applications where accurate temperature measurements are required. They are often found in laboratories, industrial settings, and scientific research facilities. These thermometers are known for their precision and reliability in temperature monitoring and control.

It is important to note that these thermometers are typically used for recording temperatures over a period of time. They can be connected to a chart recorder or data logger, allowing for continuous temperature monitoring and data collection.

Overall, Capillary Tube and Bulb Recording Thermometers are essential instruments in the field of temperature measurement and control, providing accurate and reliable readings for various applications.
