Abstract
WE have had an opportunity of examining the New Empire Analytical Balance made by Messrs. Baird and Tatlock (London) Ltd., 14-17 Cross Street, Hatton Gardens, London, E.C.I, and find that it has a number of interesting features. The fittings which are usually of brass are made in stainless steel and other parts are chromium plated. The beam is finished black, which is claimed to be fume and scratch proof, and the top edge is bevelled so that the rider can be accurately placed. The rider scale is white on black, and is easily read. The side and front doors are large and open easily, and the pan hangers are widely spaced so that large flasks may be weighed. Loose bakelite pans are supplied to fit over the metal pans and we found that these were adjusted in weight within two milligrams. The lifting mechanism worked very smoothly, and the period was reasonably short. The sensibility was very good both with small and heavy loads, and the balance is suitable for all accurate work requiring four places of decimals of a gram. The finish of the whole balance is very good, and its appearance compares favourably with that of much more expensive instruments. The agate knife edges and planes are sensibly mounted, and the robust character of the balance makes it very suitable for use by students. The boxes of weights supplied for use with the balance are of gold-plated pieces with fractions in nickel and alummium, the whole being enclosed in a bakelite block and case which will not warp, the top of the block being covered with velvet. We formed a very favourable opinion of the balance and weights, which represent exceptionally good value for the price charged, and should make a wide appeal to various types of users.
