An attractive design for industrial or commercial applications, the Century offers maximum reliability and is accurate to ±2 % of full scale (F.S.) for iron-vane meters and ±3% of full scale (F.S.) for rectifier type. The Century offers self-shielded movements which are unaffected by magnetic fields or panel mounting. Models are available to measure various voltage ranges up to 500 volts AC and are calibrated at 60Hz. These easy-to-read meters are molded in a black phenolic housing with a large glass viewing window and come in three different sizes from 2-1/2" to 4-1/2". All models offered are self-contained through 300 volts. Higher range readings require an external multiplier (supplied). This style meter is ideal for many other electrical functions.
