Pulsar Instruments Plc, with nearly 40 years of experience in the noise measurement sector, provide compliant, common sense, practical solutions for Industrial and other Noise Measurement applications.
Our range of Sound Level Meters and Dosemeters are designed with the busy professional in mind. We are constantly reminded that in the Health & Safety sector, noise measurement is only one of the many tasks that need to be implemented for compliance in the workplace. Such a user requires an instrument that can perform this duty with minimum of training and simplicity of use.
Casella Measurement was established during the reign of King George III, in 1799, by Cesare Tagliabue. A few years later, Louis Pascal Casella joined Cesare in partnership and the brand name of Casella was born. In these years, instruments to aid navigation, exploration, meteorological, medical research and photographic were invented and exported all over the world. A notable name on Casella's early customer list was Charles Darwin who used many Casella instruments in his research.
During the 19th century, the product range continued growing and Casella even exhibited at the first "Great Exhibition" held in Crystal Palace, Hyde Park, London in 1851. Products on show included theodolites and surveying equipment.
The two world wars of the 20th century saw Casella's expertise put to good use. Casella's specialisation in compasses, optics and photogrammetry equipment was used by the military in both wars. By the time the 1950s began, Casella had progressed into producing equipment for dust monitoring to be used by the deep mining industry.
Three other significant years included 1952 when Casella invented the first ever personal sampling pump, 1972 with the world's first electronic digitial integrating noise meter and 1993 when Casella launched the world's first real-time noise analysing device.
In 2006, Casella was taken over by an American company called Ideal Industries Inc. The long term future of Casella is to continue developing high quality instruments for the environmental and industrial markets, complementing the electrical, test and measurement instruments which Ideal Industries Inc develop. Soon after the takeover, Casella launched the CEL-350 Micro Noise Dosimeter, with a full array of features but contained within a smaller unit, making it perfect for use by customers such as industrial hygienists.
