Certified Rulers are an essential measuring tool used by many professionals and students alike. Precision Rulers are used by many professionals such as engineers, architects, doctors, artisans, surveyors etc. NIST (National Institute of Standards and Technology) traceable rulers help users achieve the highest level of precision in their linear measurements. NIST Traceable rulers are required under ISO and QS-9000 as well as ISO-17025 quality programs.

These days a variety of NIST traceable rulers are being made in aluminum, stainless steel, hardened and tempered steel, brass and Perspex. It's just not possible for a person to accurately measure linear distances or geometrical figures without precision rulers, precision circular scales, precision protractors or squares.

An NIST traceable ruler is available in various shapes and sizes and is well known for various purposes. An NIST traceable ruler is an essential element in the machine tool industry or any industry for that matter. The NIST traceable ruler is a calibration measurement tool developed by the National institute of Science and Technology which is responsible in regulating the measurement standards to prevent any irregularities in the commercial standards. The NIST traceable ruler has the ability to record as small as 0.000000000000001 femtometer which is the size of neutron. It has been specially designed by the institute for accurate calibration for measuring X-rays and other engineering works such as measuring the flow of various fluids and liquid substances. NIST traceable rulers help in the calibrations for gauge blocks, micrometers and calipers, coating thickness gauges and more. NIST traceable rulers are used to measure the flow of liquids and other fluids. NIST traceable rulers are used to measure temperature, pressure, density and viscosity changes of a particular fluid. This traceable ruler is generally used by scientists, engineers and technicians especially in the R& D departments of heavy industries such as Aerospace and Military. NIST traceable calibration reports are made with the help of measurements done from an NIST traceable ruler. Certified NIST traceable rulers are made of hardened and tempered steel and feature easy to read gradations on a non glare satin chrome finish. The NIST traceable ruler is an advanced measuring tool which is square in shape, fitted with a special multilayer silicon chip that is 25mm on the sides.

Due to the clutter of various stationary brands in the market, many manufacturers are now providing their customers with customized designs where an individual customer or client can choose the ruler length, ruler width; ruler thickness and ruler imprint location of certified rulers that suits their individual requirements.

Recently due to the popularity of the internet, an internet user can even buy the ruler of his choice by visiting individual websites. The use of the certified rulers varies from place to place and from industry to industry. Here is a list of professionals who use customized rulers that suits their requirements:

Architects: These professionals mostly use specialized rulers for making accurate structural designs and architectural layouts which are used in construction of buildings and skyscrapers. Most of these rulers are made of plastic or aluminum.

Engineers: Most engineers use certified rulers to adhere to the NIST standards required by quality programs such as ISO and QS-9000 as well as ISO-17025. Calibrated rulers are measuring tools used by engineers to measure linear distances. It is commonly made of metal and can be made to any length. Calibrated certified rulers are commonly used in manufacturing.

Doctors: X-ray rulers are a part of the medical equipment used mostly by surgeons during medical operations of patients. X-ray rulers are mostly used for measuring X-ray images. They are used to observe and measure the actual size of the body parts in the X-ray image. X-ray rulers also known as Radio opaque rulers can be included during X-ray procedures leaving a clear measurement right on the image of the X-ray itself. The length of a typical X-ray ruler can range from 30 cm to 130.

Apart from this many marketing and advertising professionals use special Logo rulers which helps them advertise their company or brand .
