The dilatometer DIL 402 Expedis Classic offers state-of-the-art dilatometer technology and is designed for sophisticated applications. Like all instruments of the DIL Expedis series, the Classic version features the revolutionary NanoEye measuring cell; a new dimension in measuring range and accuracy.
In classical dilatometry, the two parameters measurement range and resolutionmostly seem diametrically opposed. If the resolution goes up, the measuring range usually goes down and vice versa. NanoEye, the novel opto-electrical displacement system, features perfect linearity and maximum resolution over a measuring range which was impossible to realize until now
The DIL Expedis Classic is available as a single or dual/differential system. In both versions, the all-in-one design incorporates all hardware components which are usually necessary for precise dilatometer measurements. There is no inconvenient cable tangle nor is an external chiller required.
Expedis Classic supports your smooth production flow by maintenance-free operation, low work load, long life cycle, simplified and safe operation. The system’s sophisticated design also includes effortless exchanging of the sample holder system with no risk of distortion.
Major simplification begins with preparation of the measurement by using method-based test routines predefined by the operator.
The MultiTouch feature places the sample into the optimum position using a unique, tail-like motion. The initial sample length is then automatically deter-mined at a predefined contact force. The furnace closing is made smooth by cushioning which guarantees stable sample positioning.
Exchanging the furnace is simple and requires no detailed experience. Only a few clicks are needed to start the measurement
The controlled contact force allows the operator to measure small, delicate, fragile or foamed samples without risk of breakage and any non-reproducible deformation and to keep the contact pressure over the entire measurement time constant.
Also, this feature allows a highly repro-ducible sample length measurement independent of the respective operator. Sliding and rolling friction, stick-slip effects, etc. in the measurement system will now also be avoided.

The unique Proteus® 7 dilatometer software offers everything a user could ever want and need: It runs smoothly, provides reliable results, and it is fast and efficient. It provides a large range of functions, but – at the same time – offers a clearly-arranged user interface. Additionally, it is intuitive and thus easy to learn. But ... that’s not all. There are some more options inside which impress even the most experienced operators – particularly the Density Determination, the patented c-DTA® and the new, innovative Identify software features.
The unparalleled Identify, for the identification and interpretation of DIL measurements includes several NETZSCH libraries with hundreds of entries from the ceramic, inorganic, metal, alloy, and polymer or organic fields. Additionally, user-specific libraries can be created. They can be shared with other users within a computer network.
Identify allows the identification of unknown samples from the absolute values, the slope or the shape of a measured curve. This will also open up the opportunity to compare known samples against a variety of other samples, enabling one to make a statement about material quality. Finally, all measurements can be stored in the extensive database and are always available for identification or quality comparison.
