A leader in accuracy & quality

We have almost two century’s of experience behind us

A long history of innovation from the origination of sphygmomanometers has allowed ACCOSON to become an established leader in both quality and accuracy with continued success in modern blood pressure measurements.

With recent investment & development, our current range of products boast an excellent reputation for their quality, accuracy, durability and ease of use.

Our established history

The Company was established in 1859 by Alfred Charles Cossor following a period of apprenticeship by the founder as a glass blower. Having gained a high reputation for his skills and the quality of his products, the founder was joined by his son Alfred Charles in 1875, and then by his younger son Frank in 1885.

In 1904, Accoson produced their first glass manometer, using their glass blowing skills, known as the sphygmomanometer. A year later, Russian surgeon Nikolai Korotkoff first described the technique to measure diastolic pressure.

In 1921 Frank Cossor was joined by his son Frank Gordon Cossor, and the company expanded its products to include all types of thermometers, hydrometers and syringes. Sphygmomanometers became the main product of the company, with Adrian Cossor joining the company in 1966, the fourth generation to do so.

Recent developments

In 2018 ACCOSON was acquired by the HCE Medical Group to joins its other subsidiaries in the manufacture and supply of medical goods to the professional market.

With this acquisition, the business was relocated to new premises in Irvine, Scotland. This also allowed ACCOSON to work closely with GM Instruments, manufacturers of medical technology, together improving product research, development and manufacturing techniques.

Investment provided by the group has allowed ACCOSON the opportunity to develop our first range of clinical stethoscopes and partner to provide a selection of multi-parameter patient monitors.
