Description
| Simpson's Rectangular frequency meters
are ideal for monitoring line frequency. They are used wherever
fast, precise monitoring of complex circuits is essential. Segmental
scale frequency meters present a selected frequency range across
the entire dial face in linear fashion. Where the significant frequency
range on a conventional meter is squeezed into a quarter of an inch
of space, Simpson Segmental meters distribute that range across
the entire scale. Simpson's Rectangular style offers a popular look
with sharp, beveled edges and glass windows for easy viewing. |
