Precise and reliable conductivity measurement
Conductivity measurement determines physical and technical material properties. Ideal for quality control on manufactured products, the SIGMATEST is also useful for testing material compositions and sorting metals, alloys and scrap. Further applications include the detection of heat damage during aircraft maintenance, as well as process control in production in the metals industry.
The SIGMATEST module is used with special conductivity probes that are calibrated to traceable conductivity standards (PTB/NIST or NPL) at 20°C in the FOERSTER calibration laboratory. The calibration data are stored on the sensor and retrieved by the TCM. This enables exact conductivity measurements.
A single measurement is triggered by touch. If a scan of the surface is required, measured values can be output continuously and displayed in a time diagram.
