A measuring instrument is a device to measure a physical quantity. In the physical science, quality assurance and engineering, measurement is the activity of obtaining and comparing physical quantities of real-world object and events. Established standard objects and events are used as units, and the process of measurement gives a number relating the item under study and the referenced unit of measurement. Measuring instruments, and formal test method which define the instrument's use, are the means by which these relations of numbers are obtained. All measuring instruments are subject to varying degrees of instrument error and measurement uncertainty. These instruments may range from simple objects such as rulers and stopwatches to electron microscope and Particle accelerators, Virtual instrumentation is widely used in the development of modern measuring instruments.
Is a digital tape measure sufficient for measuring distances, or do you still require more traditional tools to gauge distances accurately and efficiently? As is often the case in construction, the best tool depends on the job itself. Here is a list of some of the most common measuring tools used in construction and the situations in which they are most and least appropriate to use.
Digital Tape Measures
A digital tape measure is also called a laser tape measure. It functions by measuring the time that it takes to register a reflected pulse from an outbound laser beam. Working according to the phase shift principle, it instantaneously calculates the distance the beam has traveled. The device then provides you with a digital readout indicating the precise distance.
Digital tape measures are accurate for both short distances and long distances up to 300 feet. They are also portable and easy to use. However, there are limitations as well. Laser tape measures should only be used indoors, and they only work if there is a solid endpoint for them to reflect a beam against. They also will not give an accurate reading when measuring porous materials that absorb light or shiny, reflective surfaces, such as metal or glass.
Bosch laser tools
Laser tape measure which is the newest entrant in the distance measurement niche.
It is an accurate and precise alternative to the traditional measuring tapes. This measuring tool uses optics and laser physics to give accurate measurements.
It works on phase shift principle, in which the reflection of the outbound laser beam and the time it takes to register the reflected pulse is used to measure the distance laser beam has traversed.
Laser tape measure can measure length from 2 inches up to 300 feet (0.05 to 100 meters)
How To Use Laser Tape Measure?
The usage of laser tape measure is also fairly simple. You have to place the device at the starting point of the distance you want to measure and aim the laser beam at the object in the end. It can be wall, pole or anything.
In case, there isn’t anything present at the end point, you can place any object to hit laser beam on. Once you have placed the tool at the right point, just hit the button and the device will flash calculation on the screen.
Laser Tape Measure - A Versatile Laser Layout Tool
Depending on how much money you have paid, the laser measure can display measurement in single or multiple units.
Also, some laser tape measures allow you to measure multiple distances and it automatically adds them together to display final result.
This distance measurement tool is accurate from +/- 1/8 inch (3 mm) to +/- 1/16 inch (1.5 mm).
Also, it can save multiple measurements in the internal memory, so you don’t have to bother about writing it down.
When To Use?
Laser tape measures are perfect when you want to take indoor measurements. You can check ceiling height or breadth of the room within a minute.
And, the best part is you don’t have to rely on someone’s help or look out for places to secure the end of the tape.
Finally, you need to make sure that you have the right tool for the right purpose. Buying a ruler to measure a room is hardly a wise decision. And, so is spending big bucks on laser measure to check straightness.
