Abstract
A draft protection device for a balance and a balance equipped with the draft protection device, wherein the draft protection device includes front and rear panels, two side panels and a top panel, and four posts which are fixedly mounted on a top cover of the balance, and wherein the posts extend vertically. The front and rear panels rest against the posts and are held in place by grooves provided in front and rear top frames which are connected to the top ends of the posts. The side panels are slidable while the front and rear panels are stationary. A friction reduction device mounted in the scale top cover so that the side panels slide along the friction reduction device.
