MEASURING TOOLS

There is a wide range of measuring tools available today, which can measure anything from angles to temperature.

Machined workpieces are measured by accurate measuring tools, such as precision vernier calipers, micrometer calipers, inside micrometers and limit gauges.

In performing accurate work a precision vernier caliper is required. The micrometer caliper, or simply micrometer, is used for more accurate measurements of external dimensions of work, such as diameters, thickness and lengths. Internal dimensions may be measured with an accuracy of 0.01 mm using inside micrometers.

The best measuring tools for checking threads are standard and limit thread gauges.

Angle gauge is predominantly used by foresters. They are held at a set distance from the user’s eye to quickly establish whether a tree is within the boundary of a plot. Angle gauges can also be used in other professions where it is necessary to measure angles.

Slope inclinometers establish the angle or gradient of a slope. These are often used in medicine to determine the angle of a person’s body, such as their back, or in working machinery to maintain safe operations.

Tape measures are probably the most commonly used measuring device of all measuring tools. Tape measures are made from long and flexible pieces of metal that have inches and centimeter measurements marked out along their length. These tools can be used to measure the length, width, height, or depth, of almost any object.

Laser measures are an alternative to traditional tape measures, and are used to measure a length of space. They work by sending out a laser beam at the press of a button, which hits the desired target and is able to measure the distance based on the detected reflection.

A compass is usually made from two lengths of metal, which are joined together at one end. One of the metal pieces will have a sharp point so that it can grip onto paper, while the other piece of metal can have a pencil attached to it. This tool will be commonly used by architects or anyone who makes technical drawings, and it can also be used in navigation.

Pressure gauge is a common measuring tool that is used to measure the pressure of liquids and gases, such as water, air, or oil. Pressure gauges are important tools in industrial and commercial environments.

Levels are used for measuring whether an angle is a level and equally balanced. There are many different types of levels that can be made from plastic, metal, or wood.

A thermometer is a traditional tool for measuring temperature. A classic thermometer will consist of a glass tube that has a small amount of mercury in the bulb at the base, and as the temperature rises, the mercury level rises up the tube to indicate a higher temperature. There are many modern types of thermometers that are digital, and used for determining a person’s body temperature.

A speedometer is a measuring gauge that instantly determines the speed that a vehicle is traveling.
