Measuring instruments are the tools of the trade for electronic engineers and
We cannot do without.
As Lord Kelvin used to say, “To Measure Is to Know”.
Besides tools, electronic instruments are interesting intricate electronic devices
of their own, rewarding objects to build or repair.
Instruments I collected
During the years when I practiced my electronics hobby, I bought electronic
instruments that I needed, if I could afford them.
During all these years, a number of occasions occurred to obtain nice
second hand professional measuring gear.
As a result, I have collected a number of mostly old instruments to use,
admire and analyse.
I have a small collection of analogue
using a moving coil meter movement.
Then, of course, a lot of valved instruments are on the
Valve Veneration page and
voltmeters and counters using
Besides valve scopes,
I have (or have had on my hands)
a number of scopes without valves (well, they do all have a CRT):
And, of course I have a number of transistorised instruments
that are nevertheless interesting. A small selection:
I also added two tube testers to my collection:
Instruments I built
I have built a number of intruments myself.
Some were very rewarding to build, some were just sources of frustration.
The ones that succeeded:
