General FeaturesInternational Instruments single/dual edgewise panels meters are a two-in-one meter design, which makes it possible to display related readings in a single unit. Meters can be ordered with zero position in the center of the scale and with accuracies of: DC: 1.5 or 2 %; AC: 2.5 or 3% (depending on the model). The compact edgewise design of the meter makes for high density data presentation and flush stacking allows the meters to be easily stacked side-by-side or top-to-bottom.Additionally, horizontal or vertical orientation offers presentation of right/left or high/low information designed for industrial, commercial, military and OEM applications. Internal white or red illumination is available on special order and scales are interchangeable as well.
