The changing phase of measurements through time
The changing phase of measurements through time As technology has advanced, there has been renewed interest in the quality of products that are being manufactured. There are trade agreements between countries and between continents to regulate the quality of products coming out of the different manufacturing areas. To assure quality, the issue of being able to carry out proper measurements cannot be ignored. As advances have been made, the standards for quality have also been raised. Ever since the ancient times, it has been a norm that in interactions between humans and trading relationships, measurements have been used and so POS system with scale is of great use. While it may be argued that the way measurements are done today have drastically changed from what used to occur in the past, the basis for making measurements has not really changed. In the past the Egyptian used the pharaoh as the basis for measurement. A pharaoh is a measurement ha is based on using the parts of the body of the king or pharaoh as they were referred to in the past. Other ancient measurements include the cubit which was also based on a body part the elbow. A cubit was considered the length of from the elbow to the top of the middle finger. In later years, we will come across the pound and foot which are measurements that came out of the United Kingdom. By the time the pound or foot measurement was losing its importance the next thing that came up was the metric system out of France. Today measurements have become even more complicated with different measuring tools some of which are complicated like Analytical weighing balance. Today the standards of measurements have been modified until we have ended with the SI metric system. The measuring instrument When it comes to making measurements, the instrument used to measure is the most important item such as industrial counting scale when it comes to making correct measurements. That is to say that how corrector incorrect a measurement is will depend on the accuracy of the instrument that was used to measure it. It therefore means that a lot of care should be given in the selection of the measuring instrument. To help chose the right instrument, you should be able to have an idea of the number of parameters that you will need. Any measuring equipment that does not have this number of parameters will be automatically eliminated. Another consideration when choosing a measuring instrument such as digital bench scale is to make sure that the instrument chosen can be able to measure the smallest amount of the item to be measured. Also, when choosing and instrument to make measurements with, its accuracy level should be acceptable for the type of measurement that you want to make. For example, if you are looking for an accuracy of +/- 1, there is no need working with an instrument that has an accuracy of +/- 5 Lian Seng Weighing Scale Co 229 Geylang Road, Singapore (65) 6741 9991 Lswsc229@singnet.com.sg http://www.lianseng-scales.com.sg/
