The new DMA 242 E Artemis combines ease of handling with the user-friendly Proteus® measurement and evaluation software. This makes it fast and easy to characterize the dynamic mechanical properties as a function of frequency, temperature and time.
Its modular design along with a wide variety of sample holders and cooling systems allow the DMA 242 E Artemis to handle a broad range of applications and samples.
Various add-on options make it the ideal device for any laboratory and a safe investment for the long-term.
for easy accessibility, handling and changing of the different sample holders
Over 30 different sample holders
for optimal adjustment of measurement conditions to material properties
Controlled gas flow (inert or oxidizing)
with optimal heat transfer on samples for defined measurement conditions
Various cooling options.
Three different cooling systems; liquid nitrogen-controlled cooling to -170°C, intracooler AIC 80 for measurements below room temperature to -70°C and compressed-air cooling to 0°C with vortex tube
Controlled force range up to 24 N
(12 N static and 12 N dynamic) for measurements of very stiff samples. Increased resolution in the measuring range 4 N static and 4 N dynamic
A stepper motor with a 20-mm travel range
allows for precise testing on materials which exhibit substantial changes in length during a DMA measurement. This is particularly important for the different static experiments available with the DMA 242 E Artemis; i.e., creep, relaxation and TMA mode.

The DMA 242 E Artemis runs under Proteus® Software on Windows®. The Proteus® Software includes everything you need to carry out a measurement and evaluate the resulting data. Through the combination of easy-to-understand menus and automated routines, a tool has been created that is extremely user-friendly and, at the same time, allows sophisticated analysis. The Proteus® Software is licensed with the instrument and can of course be installed on other computer systems.
- Logarithmic or linear scaling of the results (e.g. storage modulus, loss modulus, damping factor, resilience, length change) in up to 4 Y axes
- Display of the measurement parameters (e.g. force, displacement, amplitude, offset) as a function of time, temperature and frequency.
- Definition of values on every data plot
- Length-change curve with evaluation of the coefficient of linear thermal expansion
- Superposition (master curve) in accordance with the Williams-Landel-Ferry-equation
- Activation energy in accordance with Arrhenius analysis
- Cole-Cole diagram
- Force-displacement or stress-strain diagram
- Tension-expansion diagram for strain/stress sweeps (optional)

Sample Holders for Any Application
From liquids to highly-filled thermosets to metals and ceramics — all such materials can be measured with the DMA 242 E Artemis.
Accurate results require optimal adaptation of the test conditions to the materials and applications. That is why NETZSCH has developed a wide range of sample holders, accessories and measurement modes.
The humidity generator add-on serves to investigate the water uptake of cured samples or other organics. With the humidity generator, it is possible to create relative humidity values of between 5% and 90% in the temperature range from RT to 70°C.
The DMA 242 E Artemis supports the OmniCure S2000 UV lamp for studying light-induced reactions such as the UV curing of adhesives, inks or paints.

The modular design of the dynamic mechanical analyzer DMA 242 E Artemis secures its viability as a long-term investment.
Sample Holders, Calibration Materials and Other Accessories
For many decades, steel was the primary material used in the automotive industry. In more recent years, a shift toward electric motors has increased the popularity of lighter metals. Technological advancements make it necessary to continuously seek lighter and lighter materials, but without sacrificing the required stiffness over a broad temperature range. The key to reducing vehicular weight has been found in the use of fiber-reinforced polymers.
