Asking TEA fellows, especially from Germany, any comment about this German made multimeter ? (photo attached) As I'm not familiar with the brand.
I've been offered locally, apart from my weak heart seeing moving coil meter , what interested me is it claims its a true RMS and also has a switch for averaging too, and AC+DC or pure AC in analog display.
Or any other comments maybe ?
The brand is Lucas Nülle, their website can be found here:
https://www.lucas-nuelle.com/They are specialized in producing measurement instruments for education and research, perhaps you are familiar with the brand PHYWE (PHYsikalische WErkstätte - physical workshop) which exists since 1913 and belongs to Lucas Nülle since 1988. (

Your meter claims to be undestructable for voltages up to 1kV and for currents up to 30A and from the build quality it is one of the best you can get, imho.
