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 square 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 to measure various current ranges. In addition, this style meter can be ordered to measure motor load current. This style meter is ideal for other electrical functions.
