MINIMESS ® –
THE GOLD STANDARD IN TEST POINT COUPLING
Using innovative solutions to set
industry trends
Hydrotechnik has long been on the cutting
edge when it comes to hydraulic testing
technology. In 1964, Hydrotechnik launched
the Minimess® - plug-in test point coupling
with a ball sealing mechanism. The inventor of
this revolutionary technology was our company
founder himself, Ulrich Baumgarten. In the past,
Ann-Kathrin Sanchez-Bombe

pressure was measured using a fixed mounted
The Original Minimess® pressure gauge, and the only way to measure
the pressure was to shut down the entire system, a time-consuming process. Thanks to this revolutionary
technology, production would no longer need to be interrupted.
Revolutionary soft-seal technology
In 1982, staying true to its motto, “in progress we trust”, Hydrotechnik patented a leak-free test point
soft-sealing technology. Its precision and ease of use makes it the product of choice for performance and
safety, especially when it comes to using hydraulic systems in environmentally sensitive areas or in the
gas industry.
p/T test points: Using today’s technology to prevent tomorrow’s problems
Technological developments in the fields of automation and robotics have made it possible to measure
temperature and pressure at the same testing point. Hydrotechnik’s engineers put their heads together
and developed the p/T (pressure/temperature) test point. They designed the spring-loaded valve body
so that it was longer and could act as a thermowell that extended into the fluid being tested: When
the temperature sensor is screwed into the test point, the valve opens and floods the thermowell. This
technology ensures that the fluid temperature is accurately transferred to the temperature sensor.
Dependability and quality
Modern automation technology combined with an integrated leakage detection system, ensures that
Hydrotechnik delivers high-quality products, a high level of process reliability and zero leakage. There
is currently a wide selection of technologically-advanced test point couplings available to the mobile
hydraulic industry; however, because of their commitment to environmental safety standards and their
goal to improve their customers’ economic efficiency, Minimess® test points have become the industry
leader when it comes to modern test point technology.
