Permeation/Materials Testing Instruments: We now offer a wide range of material testing devices for checking the permeability of various materials as well as their physical properties. Films, plates, vessels and other packaging materials can be tested, for example, for their water vapor or gas permeability (gas analysis) as well as their impact strength and mechanical resilience during friction or shearing.

Colour and Haze – Test equipment for measuring colour and haze for mobile applications and in the laboratory. We essentially offer two groups of testing devices for measuring colour and haze of materials, surfaces or liquids. They are the ideal instruments for laboratory and field use. [more]

The Tiedemann Laser Microphone – Unique Acoustic Measuring System for Process Control or Non-Destructive Material Testing (NDT) is a rugged, diaphragm-free, broadband microphone designed for acoustic applications in gases in the mPa-to-Pa range. The frequency response extends into the MHz range. For the detection of soundwaves, conventional microphones use diaphragms or other moving parts as mediators between the incoming acoustic and the resulting electrical quantity. [more]

Roller Alignment at a Glance
The electronic nip analysis system measures and calculates the nip width at different points along the rolls in real-time. The system Sigma-Nip consists of a series of sensors that are placed between the rollers together with an analysis program. The sensors can be positioned quickly and easily. They survive high pressures and are able to measure simultaneously with high accuracy and reproducibility. It is the ideal solution for setting all kinds of rolls: Sigma-Nip, Digi-Nip 2 and Auto-Nis.
