Scale is a measuring instrument for determining the weight or mass of an object. Weighing scales are used in many industrial and commercial applications, and products from feathers to loaded tractor-trailers are sold by weight. Specialized medical scales including infant medical scales, and bathroom scales are used to measure the body weight of human beings.
Spring scales measure the weight by balancing the force due to gravity against the force on a spring, whereas a balance or pair of scales using a balance beam compares masses by balancing the force of gravity due to the mass of an object against the force due to gravity of a known mass. Either type of scales can be calibrated to read in units of force such as Newtons. To view the details about scale and scale service center details and contact details to visit the site given below.
