Description

The 185 series of edgewise panel meters, are 2 1/2" meters designed to handle applications where panel space is at a premium. The 185 series meters can be mounted in a horizontal or vertical orientation and can be flush mounted in space saving clusters or with a bezel. They are accurate to within ±2% of full scale in DC and ±3% for AC. Unlike the 280 series, these metes have a thicker profile, providing a larger scaling area that translates into a higher resolution scale with large divisions and easily readable numerals. Special scaling and color swatches are possible, for those applications that require complex scaling.
