Simpler processes and measurements. Better results.
The Tensormeter is designed for precision measurements of resistance and voltages. It unites the benefits of both Lock-in amplifiers and source/measure units through an innovative flexible architecture.
► Simultaneous sheet & Hall measurement (RX, RY, RH)
► Evolution of the van-der-Pauw concept
► Replaces Lock-in Amplifier, Source Measure Unit, Digital Multimeter, Analog Matrix Switch
► Full precision restored by post calculation
► Extremely low noise allows short integration time
► Massive measuring time savings
The new standard
The resistivity of materials in a Tensor quantity, which contains 6 independent components for 3d objects and 3 independent components for thin films.
Traditional 4-wire resistance measurements attempt to measure exactly one of these components. The selection of this desired component happens via the contacting layout of the sample structure. This has lead to the famous Kelvin and Hall type 4-wire measurements. However, limitations in fabrication accuracy always give rise to errors in these fixed-geometry 4-wire measurements.
The Tensormeter solves this challenge by measuring the resistivity tensor, which makes measurements resilient against measurement geometry changes and provides greater precision.
