Voltmeters

[tbone]

Ah the good old days, metal cases, moving coils, quality packaging.
How many of you remember these........

This is my collection of `pocket watch` voltmeters...and 2 that obviously aren`t.

That's impressive Tim. I've seen the big boxed ones before, but never the smaller ones. Is this something new, inspired by your ever growing collection of stationary engines, or have you had these for a while?

The small ones all date from the middle 1920`s to the 40`s.
The black bakelite one is from 1949, but my `best` one is the wooden boxed one.
Its a model number 45, serial no. 18534 and was produced on nov 26th 1938 by Weston`s, a major name in early meter technology.
It`s housed in a beautiful mohogany case, bakelite again being used for the meter face.
Quality craftmanship, accurate to 0.0001 @ 20 deg celcius.

I`ve had some of these for quite some time, the small one with the single prong was given to me many years ago by a chap in the motor trade, he used it for testing battery voltage (they aren`t automotive items but mainly used in the radio repair business), and it became mine when he got a `modern` one  .
I keep meaning to sort out a display case, instead of stuffing them in a draw! and thats why they are out now, thought i`d share them before shutting them away again.

There's something very cool about old technology.
Very nice mate.

yes numbers etc that you can read nothing much to go wrong rather than some numbers showing on some eletronic gizmo. i'm sure me dad had one of the single prong ones. might still have it laying around somewhere.

When I started in the "business" Tim, the standard meters for calibrating day to day instruments were as per your mahogany cased model, both moving coil, and of course moving iron for AC appliances.No doubt you remember to read of via the mirror background, and not the pointer?, interesting....Morrag

I have to confess that despite the majority being in working order, i don`t actualy use them! tsk tsk at me.

Nice collection.

Got a few myself. An old Avo, A few of those small ones. An ex Army jobbie that  does RF measurements too.


I have to say though a good quality digital one is great. I have two good digital meters and they are extremely practical accurate and useful. (small too) 


They do tend to get used constantly.
