Description
| Look to the 250° Long Scale analog
meters for a full 250° readability that provides more than double
the scale length of the standard 90° or 100° movements.
Simpson’s 250° panel meters are designed for applications
that require high-resolution readings - all in a compact and attractive
design. They are rectifier type, self-shielded, moving coil instruments
with non-magnetic pivots and spring backed jewels. The movement
construction allows the meter to be mounted on steel panels. These
easy-to-read meters are available in either sealed round metal or
in molded rectangular phenolic cases with glass windows. The zero
adjust is conveniently located on the external front portion of
the meter. Two different standard sizes of 3-1/2” and 4-1/2”
are available in selected voltage ranges. This style meter is ideal
for other electrical functions. |
