Weston Model 1 Ammeter
Purchased
in 2020, I have wanted this particular one for a while and bought this
one for $30 shipped from Ebay. What I like about this one is the
large movement that is shown off by the glass window. It also has
a varnished wooden base and a red case. Many of the Model 1s have
a black case. It is rather small and heavy so it has a nice heft
and cuteness to it.
Weston Model 1
Weston Model 5 Lab StandardThe
Model 5 has some interesting features. First of all, it is very
large. The base is wider than 15". It has a bubble level to
ensure the movement is set up as designed. It also has a
thermometer built in. Presumably to be part of the reading in
case that makes a difference to the meter. Finally, it has a
mirrored scale for consistent and accurate readings. In addition,
the scale is really huge (which is the point of the large size of the
overal device), with many fine divisions. This provides the
highest resolution readings.
I collect meters that have the mechanism
(with the brightly colored enameled wire coil) showing.
Others to be added in the future.
