SIGMATEST is a portable measuring instrument for determining the electrical conductivity of non-ferromagnetic metals in accordance with the eddy current method. The unit determines physical and technical material properties. It is typically used for controlling the quality of manufactured products, testing material combinations, and sorting metals, alloys, and scrap metal. The unit is also used for the maintenance of aircrafts, determining heat damage, and in-process controls during production and processing in the metallurgy sector.
It features five different excitation frequencies and extremely high measuring accuracy. The unit retains this high level of accuracy even at a high frequency of 960 kHz, making it possible to measure very thin workpieces with great precision.
The measuring instrument is able to automatically standardize the measured value of the electrical conductivity to 20°C thanks to integrated temperature compensation.
Your advantages at a glance:
- Five measuring frequencies 60, 120, 240, 480, 960 kHz
The high frequency of 960 kHz allows accurate electrical conductivity measurement on very thin pieces - 50 measurements per second
- Easy operation in either touch or continous mode
- Internal and external temperature compensation
- Measurement possible up to 0.75 mm distance from the test item
- Measurement range from 0.5 to 65 MS/m (1-112 % IACS)
- Remote control by an external PC is possible via Ethernet standard RJ45. The interface allows complete control over the instrument and an integration in automated systems
- SD-card slot for saving nearly an unlimited amount of test data
- Probe characteristics are directly saved on the probe and automatically read by the device
- Multilanguage operating system
- Robust device design for operation on site
