The Brand-New NETZSCH DIL 502 Expedis® Dilatometer: The Future of Low- and High-Temperature Dilatometry
For decades, NETZSCH has set benchmarks in dilatometry — and now, we’re raising the bar again. The new DIL 502 Expedis® combines cutting-edge measurement technology with an intuitive user interface to deliver precise insights into dimensional changes across a wide variety of materials.
From Ceramics to Composites
Originally developed for SinteringSintering is a production process for forming a mechanically strong body out of a ceramic or metallic powder. sintering studies in ceramics, dilatometry (DIL) has become indispensable in materials science. Today, the NETZSCH DIL 502 Expedis® measures metals and alloys, glasses, polymers, salts, and composite materials, providing not only data on linear thermal expansion but also information on volume and DensityThe mass density is defined as the ratio between mass and volume. density as a function of temperature.
Which Information Can You Get from DIL Measurements?
- Linear thermal expansion
- Coefficient of thermal expansion (Coefficient of Linear Thermal Expansion (CLTE/CTE)The coefficient of linear thermal expansion (CLTE) describes the length change of a material as a function of the temperature.CTE)
- Softening point
- Glass transition
- Phase transitions
- SinteringSintering is a production process for forming a mechanically strong body out of a ceramic or metallic powder. Sintering temperature and shrinkage steps
- Influence of additives and raw materials
- Decomposition reactionA decomposition reaction is a thermally induced reaction of a chemical compound forming solid and/or gaseous products. Decomposition temperature of, e.g., organic binders
- Anisotropic behavior
- Volumetric expansion
- DensityThe mass density is defined as the ratio between mass and volume. Density change
- Caloric effects by using c-DTA
All of this is made possible by the powerful Proteus® software – enabling fast, reliable, and intuitive dilatometry measurements. With its user-friendly interface and comprehensive evaluation features, even complex dimensional analyses become efficient and accessible.
Advanced Technology, Simplified Operation
The heart of the DIL 502 is the NanoEye measurement system, delivering nanometer resolution across a measurement range of up to 50 mm.
This optoelectronic system enables controlled force application (10 mN to 3 N) with unmatched precision.
Furthermore, the new touchscreen panel makes everyday lab tasks smoother — from sample length detection and gas flow control to starting a measurement or viewing live data.
Flexible Configurations for Every Need
Choose between the Classic, Select, and Supreme versions based on your application requirements—from quality control testing and low-temperature measurements to ultra-high-temperature measurements (ranging from -180°C up to 2800°C with a graphite furnace).
Each version supports a range of sample holders and accessories to match material types and temperature profiles, including graphite, alumina and fused silica options. The DIL 502 Expedis® is designed to handle a broad range of sample sizes and shapes, with typical dimensions of 25 millimeters in length and 6 millimeters in diameter. However, it can accommodate larger samples up to 52 millimeters in length and 19 millimeters in diameter.
For even more flexibility, the DIL 502 Expedis® supports dual furnaces, a double measurement system, vacuum compatibility and an optional air intercooler down to -60 °C.
Benefit from our Unlimited Warranty!
Investing in NETZSCH’s high-quality laboratory instruments is a smart long-term decision that provides reliable performance and lasting value. Whether you're conducting cutting-edge research or ensuring precise quality control, your equipment needs to deliver reliable performance for the years to come. That’s why we offer something truly unique:
Glovebox Version Available
In cases where materials are very sensitive to oxygen or humidity, or operators must be protected from specimen properties, the challenge can often only be managed by using a glovebox.
The DIL Expedis® Supremeglovebox version was specifically developed for such applications. The system’s electronics are positioned outside the glovebox, and an optional remote control unit allows for easy movement of the pushrod or furnace from outside.
