A set of calipers.
A micrometer is a common instrument used to measure the external and internal diameter of a test tube. It is a precision tool that provides accurate measurements of small distances. Another option is a caliper, which can also be used for measuring diameters.
Vernier caliper
Calipers measure the internal or external dimensions of something.
A manometer instrument is used to check the alignment of two shafts.
A caliper can be used to measure the internal and external diameter of a tube with about a 5cm bore. Make sure to use the appropriate jaws of the caliper for accurate measurements. Alternatively, a micrometer can also be used for precise measurements of the tube's diameter.
The instrument used to measure the diameter of spherical objects is called calipers.
A Vernier caliper, or a micrometer can measure diameter real well, and from that it's easy to calculate area.
A vernier caliper or a micrometer can be used to measure the internal diameter of a beaker. These tools provide accurate measurements of dimensions, including internal diameters, with precision.
A digital caliper is commonly used to measure the internal and external diameters of a test tube with precision. This tool allows for accurate readings by using its jaws to measure diameters and display the measurements digitally.
Astronomers use a variety of instruments such as telescopes and radar to measure the diameter of planets. One commonly used instrument is a laser range finder, which can be used to determine the size of a planet by measuring the time it takes for a laser beam to bounce back to Earth after being pointed at the planet's surface.
The jaws of the vernier calipers are used to measure the external diameter of a cylinder. The jaws are placed around the object being measured, and the reading is taken from the scale on the main body of the calipers.
A caliper is a tool that can be used to measure both internal and external diameter accurately. It consists of two arms with measuring jaws that can be adjusted to fit the size of the object being measured. The different types of calipers include digital, dial, and Vernier calipers.
