Avo multimeter model 72

This is a more accurate and virtually identical meter to the earlier model 71. The 1Amp fuse has been omitted but otherwise much the same.


Unfortunately the meter movement was found to be open circuit


The Taylor model 128 is almost identical except it does not have the 2.5Amp range


You will find more information here about these instruments and other similar models. AVO produced a range of the smaller multimeters such as this which are described here 


AVO produced the "70 series" range of analogue pocket meters with 2000 Ohms/Volt sensitivity and 3 inch scale lengths at the beginning of the 1970's. The following is from a 1972/3 trade catalogue.
