The edgewise family of panel meter products were designed to handle applications where panel space is at a premium.The 280 edgewise series may be mounted horizontally or vertically and meet ANSI C39.1. The Yokogawa line of edgewise meters are accurate to within ±2% of full scale in DC and ±3% for AC and come in a variety of sizes and ratings.
The thin element design provides the maximum performance in the smallest of spaces. Available in 1 1/2" to 3 1/2" sizes for vertical or horizontal mounting. They can stand alone or be stacked in space-saving clusters. Built-in magnetic shielding prevents interference among meters and removes the burden of special calibration. |

| The absence of friction
resulting from this permits greater sensitivities
and provides more rugged meters.Common
failures of conventional meters subjected to
shock testing are cracked jewels and/or
blunted pivots. |
