Until now, testing very delicate or miniature mechanical parts – such as bearings, springs, microwires, organic fibers, and micro-electro-mechanical devices – wasn’t possible with conventional universal testing machines. Anton Paar’s UTM Micro changes that. Based on the renowned MCR rheometer, it combines highly sensitive MCR technology with proven modularity, an integrated extensometer, and a load cell. This lets you go far beyond tensile tests and tackle challenges in areas like DMA and optical methods.

Key features

A whole new world of low-force universal material testing

UTM Micro opens up a whole new world: Test small components down to 0.0005 N, torques down to 0.2 nNm, angles of 6x10-8 degrees, and displacement accuracy of 0.01 µm – across a never-before-accessible micro range. With our universal testing machine, say goodbye to expensive self-made or limited commercial solutions, and complicated back-and-forth with external testing labs. Take full control of product development, research, and quality checks.

Test your mechanical parts under real-life conditions

Set precise testing conditions with temperature capabilities from -170 °C to +1,000 °C and humidity from 5 % to 95 % RH. UTM Micro also supports testing in an inert gas atmosphere, reducing oxidation and preventing sample contamination – a capability unmatched in this market. Our temperature devices ensure exceptional uniformity, with gradients as low as ≤0.1 °C for absolute, reproducible results. Pre-calibrated force and torque sensors mean temperature and humidity functions are ready to use immediately, with no long waits to reach target conditions. And with heating rates of up to 60 °C per minute, you can accelerate your testing workflows significantly.

Choose from a range of variable-geometry grips and fixtures

The future is yours: Adapt the instrument to your specific needs via 200+ accessories. Our engineering team can quickly create competitively priced custom accessories in-house. We have automation and robotics solutions too. From tensile tester to micro torque tester, UTM Micro gives you the flexibility you need for years to come.

More than ‘just’ a universal testing machine

Make UTM Micro exactly what you need – whether it’s a dedicated mechanical testing machine or a multi-purpose performer combining several methods. It can function as a rheometer, tribometer, and DMA device, and it supports optical methods for deeper insight into component behavior. An extensometer and load cell come integrated as standard.

Save time and personnel costs

The easy handling of our universal testing machine saves you time and personnel costs, as no experts are needed to handle the device. Unique usability features integrated into the device and software increase throughput. We’ve designed every component and created every handling step to be part of a smooth and intelligent whole: The patented Toolmaster technology automatically recognizes measuring geometries and accessories and transfers all relevant parameters to the software without the risk of errors. QuickConnect coupling allows one-handed, one-second exchange of measuring geometries, testing fixtures, holders, and clamps.

Micro mechanical testing for various applications

Small mechanical components are used across countless products. To understand how they perform under specific conditions – and to predict their lifetime – you need to put them to the test.

Typical industries and applications include:

Precision mechanics (machine elements, springs, threads, gearboxes, wires, watchmaking)
Microelectronics/semiconductors (micro motors/turbines, semiconductor fibers, fiber-optic torque sensors, devices, SMD drills/torques, electronic switches)
Medical technology (actuation force syringes, stents, piercing force, safety closures)
