Description
| An attractive design for industrial or
commercial applications, the Century offers maximum reliability
and is accurate to ±2 percent full scale (F.S.) on all readings.
The Century offers selfshielding movement which is unaffected by
magnetic fields or panel mounting. Models are available to measure
current ranges up to 500 amps. These easy-to-read meters, molded
in a black phenolic housing with a large glass viewing window, come
in four different sizes from 1-1/2 to 4-1/2 inches. The 1-1/2"
meters are selfcontained through 10 amps, whereas the 2-1/2",
3-1/2" and 4-1/2" meters are self-contained through 50
amps. Higher range readings require an external shunt. Custom dials
can be ordered to fit your specific application. This style meter
is ideal for many other electrical functions. |
