For more than 40 years, digital density meters have been a reliable alternative to hydrometers and pycnometers. During this time, many improvements have been made to increase the accuracy and precision of these instruments. Several new technologies have emerged in the latest generation of digital density meters. These technologies provide complete transparency and traceability of the sample filling and measurement process. With these added abilities, the industry has reached a new level of quality and confidence in measurement results.
In the early 1960s, a renowned Austrian scientist, Hans Stabinger, invented the oscillating U-tube principle. With his colleague, Hans Leopold, he soon developed a working prototype. In 1967, the first digital density meter became commercially available, marking a turning point for density measurement and replacing old-fashioned hydrometers and pycnometers.
