Mercury RT® IndustryView leaflet
Deformation measurement of samples during material testing with use of the Video extensometer Mercury RT® allows applying multiple virtual probes (Movement Sensors) on markers and advanced image features to be tracked, including the natural pattern of the sample surfaces.
The Mercury RT® system enables the user to analyze the measurement either in offline or online modes, thus high-speed cameras can be used. The computation is performed in real-time, where the computed values are transferred to a connected test rig, either via analog or digital outputs.
Typical use is the determination of various material properties (tensile tests, uni/biaxial properties, contractions), measurement of large strain rates, high-speed testing, vibration measurement, crack propagation, dynamic testing and quality control.
Mercury RT® ModularityView leaflet
A non-contact optical measurement technology has made a major step in terms of speed and accuracy in recent years. The Mercury RT® measurement system shows in practice following benefits - it measures general deformations (strains and displacements) and any distance change between two markers set in any axis with high sub-pixel accuracy. The Mercury RT® is based on digital image correlation technology (DIC).
The common resolution of standard system is within 500 nm and 5 µm. The system fulfils class 0.5 or B-1 of classification according to ISO 9513 and ASTM E83. In certain camera use case, the system resolution reaches the level of 100 nm - 500 nm and system fulfils the class 0.2. The strain resolution can reach 10 microstrains.

SYNCBOX is a universal synchronization unit for controlled triggering dynamical, periodical or vibrating process with optical vibrographic system. The unit enables to synchronize up to four independent outputs with connected devices. Synchronized device is triggered by generated voltage pulse. SYNCBOX allows to generate signal with adjustable amplitude and frequency for optional frequency sweep. This feature is especially suitable for control an amplifier or a similar block for driving dynamical test machine, shaker etc. Information about parameters of captured and/or generated signals are sent via USB, Bluetooth using the API.
