The dielectrimeters SEFELEC 56-D and SEFELEC 506-D from EATON allow dielectric strength tests in AC and DC and insulation measurements to be carried out; Thanks to the DSP technology and the DUAL-ARM-Core architecture, a high level of stability and repeatability is achieved. The high accuracy and measuring speed are suitable for quality control or entry control departments. The sequence mode makes the SEFELEC 56-D and 506-D easier to use and integrate into a controller or test bench.
