About Casella Measurement

Cesare Tagliabue established the original company in Holborn, London in 1799 during the reign of King George III. Within a few years Louis Pascal Casella joined Cesare in a partnership and the new Casella name was born. In the early years the product ranges being exported around the world included exploration, navigation, photographic, meteorological and medical research instruments. Our early customers included Charles Darwin and Dr. Livingstone who used many of the early Casella products on their travels of discovery. During the 19th century, the product range continued to grow and Casella exhibited instruments including theodolites and surveying equipment at the first 'Great Exhibition' held in the Crystal Palace, Hyde Park London in 1851.

Casella in the 20th century

As the two great World Wars of the last century raged, Casella's expertise in optics, compasses and photogrammetry equipment was put to good use by the military. By the 1950's Casella had designed and built a significant amount of dust monitoring equipment for the deep mining industry, including a number of industry standard products. In 1952 Casella invented the first ever personal sampling pump, used for monitoring exposure to dust, in 1972 we launched the world's first electronic digital integrating noise meter, in 1993 we launched the world's first real time noise analyser.

About CEL

CEL Instruments have been manufacturing high quality instrumentation for the measurement of noise and vibration since the early 1970's. Originally formed from the company Computer Engineering Limited, a British company specialising in the design and manufacture of computer related equipment, CEL rapidly became well known for designing state of the art noise products in the UK. In 1998, Casella acquired CEL Instruments, manufacturers of innovative noise monitoring equipment. The natural synergy formed from this integration allows the combined new company, Casella CEL, to offer a broader and more comprehensive product range to both the occupational and environmental market sectors.
