History and milestones

Refining our deep knowledge and experience in acute care diagnostics since 1954

Our role in the history of blood gas testing



Engineers Børge Aagaard Nielsen and Carl Schrøder found Radiometer to develop measuring devices for the growing radio industry in Denmark [1].



Gotfred Haugaard, an assistant to famed chemist S.P.L. Sørensen of the prestigious Carlsberg Laboratory, contacts Radiometer. Haugaard asks Radiometer to develop an analytical device for the detection of the acid-base (pH) level in liquids. This collaboration would soon result in the first commercially available analyzer to measure the pH of a blood sample. [1, 2]


As the polio epidemic sweeps across Europe, many patients, including children, are at risk of respiratory failure. Laboratory head and professor Poul Astrup and anesthesiologist Bjørn Ibsen discover how to improve the diagnosis and treatment of patients by measuring the pH value in blood using Radiometer’s pH meters. [2, 3]


The groundbreaking discovery forms the basis for Radiometer’s entry into medical technology with Radiometer developing the world’s first commercially available blood gas analyzer [1].

Today Radiometer continues to advance acute care diagnostic solutions with dedication, clinical evidence, attention to detail and heartfelt passion.

A legacy of innovation

In our line of business innovation doesn't occur overnight. Creating impactful innovations requires uncompromising persistence and passion, which must be maintained for years.

We believe that breakthrough results are made by specialists rather than generalists. We are driven to push the boundaries of innovation to find new and improved solutions.

Radiometer is built on a legacy of innovation:

  • In 1954 we launched the world’s first commercially available blood gas analyzer

  • We continue to expand our point-of-care testing menu, the most recent additions being creatinine and urea

  • We support patient blood management by ensuring you only get the amount of blood you need for a full panel of results
  • We shorten the time to result

  • We collaborate with leading universities and institutions on point-of-care research projects

  • We share our insights on the latest scientific knowledge information within our field through the open and non-commercial site
