ESI 277 capacitance bridge
copyright publication jan-june 1963
This nice bridge was a gift from my friend Arnold. It is a capacitance bridge and made in august 1963. It is rackmount and I once have seen a B&W picture of one in a 19″ rack together with an oscillator unit and detector unit. I think that it, just like the GR-1620, could be bought as a combination that had its own type number.
