The first density measuring oscillator, which was built in 1966, had a hollow sphere on the front end which was filled with the sample and its natural oscillation was stimulated by means of a system of solenoid coils.
The first digital density meter, the DMA 02C was presented at the ACHEMA in Frankfurt, Germany, already in 1967.
August Höfler (aka “der Bürstl“) of Bartelt, Graz, one of our very first partners, contributed the glass blowing work for our devices with great personal commitment and phenomenal skills from the beginnings in 1965 until he retired. Thus he contributed essentially to the success of many projects.
A simple density meter of the early 1970s with limited precision.
First half of the 1970s: Separation of electronics (DMA 60) and measuring cell (DMA 602).
The first density meter with a built-in digital calculator.
Density Measurement in Process Technology
Measuring cells were developed for specific applications, which were operated in combination with a standard laboratory device. For example, an external density measuring cell DMA 401W with an upstream heat exchanger is shown here.
Early 1980s: Battery-powered portable density meter with direct display.
Digital density meter for laboratory use.
We moved into the new company building in the summer of 1987.
Entry-level device for the measurement of density with award-winning design.
Our experiment in outer space.
A new method of measuring the hematocrit level in blood online.
In the Beer Monitor, a density and sound velocity measuring cell are arranged in the DPRn housing in such a way that the same sample stream flows through them.
In beer, for example, the alcohol and original extract content can be determined online from the density, the sound velocity, and the temperature of the sample. But this device is also used for analysing other ternary (three-component) systems.
Early 1990s: a new generation of the density meter, with a reference oscillator and a Peltier thermostat.
Portable density meter, also available in an explosion-proof version.
In 1997, we began to explore the principle of a new rotational viscometer.
The first series of Stabinger Viscometers.
The first build of a device working according to the viscometer principle. This version was already built in small lots. Yet, fundamental flaws required fundamental improvements.
Combined measuring of density and sound velocity with the highest precision.
A new, revolutionary viscometer.
DMA35N, the portable density meter tried and tested thousands of times, is re-engineered.
High-end laboratory density meter Generation M.

A partnership lasting for decades is ending. We are making new friends.
The team of Stabinger Messtechnik and their new employer Mettler Toledo GmbH is looking forward to future challenges and goals.
As the company is no longer working in actual reseache an developement ist name has changed.
The Hans Stabinger GmbH is now run by Hans Stabinger and his daughters Susanne, Elisabeth and Johanna as property management. The buildig of the lab is still owned by this company.
In strange times of the pandemic Hans Stabinger could celebrate his 80 th birthday all healthy but only with the close family.
