Gossen Metrawatt have clones of their MetraHit 28s meters under AvoMeter M3045S, Siemens B1105 and Drantech Ultra M230H, ST Gamma 20, Unigor 380 or 390, Rishab RishMulti 20 (but have less functions)
I had the AvoMeter clone, and a Metrahit 28s the input protection is slightly different in parts, it loose the cat IV specs ... but same quality fuses.
Slow in display speed, but incredible features not found on recent meters, ditched my flukes, they lost me with the 83 series 5 models (ac modes by default, erk could not stand it).
Now added an Gossen 29s to my collection.
