History and milestones

Radiometer has been providing innovative solutions since 1935

In 1935, the two engineers, Børge Aagaard Nielsen and Carl Schrøder, founded the company, Radiometer, to develop measuring devices for the growing Danish radio industry.

A few years later, Radiometer was contacted by the Carlsberg laboratories and asked to develop an analytical device for the detection of the acid-base (pH) level in liquids. This soon resulted in the first commercially available pH meter. 

In 1952, as the polio epidemic swept across Europe, many children were at risk of respiratory failure. The head of laboratory, professor Poul Astrup, and anesthesiologist Bjørn Ibsen discovered the right diagnosis by measuring the pH value in blood using Radiometer’s pH meters.

This ground-breaking discovery soon formed the basis for Radiometer’s entry into medical technology and further innovations within acute care testing. 

Radiometer remains committed to being a leader in acute care testing technology.
