AC DC Voltmeter/ ammeter (picture heavy for those on steam powered aethernets)

Post  Captain Dave Hawker on Wed Oct 01, 2008 3:20 pm

Whilst cleaning out our workshop my collegue and I found this wonderfully crafted item.


Its an old English Record Voltmeter/Ammeter for both AC and DC, would have been cutting edge in its time I believe.
We have contacted the manufacturers and are waiting to hear back from them to find if they know a date of its production.

It has storage on board for several CT's ranging from 1 Amp to 600 Amps (quite a range for an old hand held device).



the CT's are fixed to the device underneath via some thumb screws.


Under the black cover seen on the first picture is the scales for Volts (top) and Amps (bottom). The Ammeter scale can be rotated along the horizontal via thumb screws on the outside to change the scale to suit the CT that is being used, again from 1 Amp up to 600 Amps.


It also has a rather attractive leather carrying handle.



So anyone care to guess an age, or possibly knows someone who used to work For the old Record Electric company?

The Record Electric company probably made voltmeters and ammeters, and there were millions of these kind of obscure electric-device-building companies; most have faded into history, forgotten and unknown.
It's nice but it doesn't look very old. If I could have a look inside at it's workings I could give you an age estimate. Is there not a year on the case or voltmeter/ammeter faces? Usually on such big and professional devices there is a date! Some of the slightly more modern meter companies dated thier meters on the face plate.

We can't see a date anywhere on it I'm afraid, it does have what appears to be a serial number on the face plate. I know it won't be very old compared to some items found by steam punks here, but in my profession this item might as well be as old as an abacus to someone who works in I.T.
I'm not as desperate to find out its age to warrent opening the box up, I fear my carpentry skills are not up to repairing any damage that would cause.

And The Record Electric company is still going strong (founded in 1911) http://www.record-electrical.co.uk/

As stated in my origonal post I have spoken to them to try and age this piece.

Just based on what I have in my collection, I'd say mid-1930s to early 1940s. Though if it was made in the UK it may even go later - war shortages meant that some electrical/physics/lab gear was made looking like that into the early 1950s, as I discovered when restoring a Wheatstone bridge some years ago.

Then it all went galvanised and black plastic...

Hi All,
can't swear to it, but this looks really familiar. My grandfather was in a reserved occupation in WW2, and was an electrician, particularly doing work on the underground. I'm sure he had one of these when I was a kid. I guess it must be around the mid 1930's.
