Try looking for the history of the company AVO. They were pioneers in that area.

First one I ever used was an Avo 7, Avo website is http://www.avo.co.uk/uk/about/index.php

If you want a rarity to include, Sinclair Electronics made one of the first electronic ones that used fluorescent display tubes (Nixie?). It used a plastic case that incorporated hinges that broke almost immediately. I think that bit of Sinclair became Thandar (now Thurlby http://www.tti-test.com)

Hi,

Yes I remember uncle Clive showing us the PDM35, (PDM35 = Personal Digital Multimeter with 3.5mm led display). It was built into a calculator case, with a slide switch selector. Planet Sinclair has a section which deals with the range of multimeters.

I bought my first computer from Clive Sinclair's company. It was a ZX80 kit.

The first practical "multimeter" was the Simpson Model 260, an analog volt-ohm-meter developed in the late 1930s and used throughout WWII by all Allied forces.

GE, Yokogawa, AVO, Biddle, and Fluke are also pioneers in multimeters.
