The weather indications on a standard barometer are very often inaccurate when compared to outside conditions owing to the fact that they only measure air pressure. With the combination of the varying factors included on this simple but deceptively complex desktop instrument, it made the process of domestic weather forecasting a much more accurate and simple process and it remains just as useful to those interested in weather forecasting today. Negretti & Zambra were a leading name in the production of meteorological and scientific instruments and had a company history dating back to 1850 although their parents were amongst those Italian emigres that bolstered the British meteorological instrument making industry at the turn of the century.
Throughout their long and esteemed history they exhibited at British and international industrial fairs and became makers to both Queen Victoria and Edward VII. Owing to changes in the business, the firm ceased the public retailing of scientific instruments sometime around the late 1960's and continued with a focus on the aviation industry in numerous guises until its eventual liquidation in the year 2000. They are today perhaps the most collected of the scientific instrument firms which bears testament to the quality of their work.
