EW SERIES

EW SERIES

Traditional panel meters with upright scales & clear glass fronts with Round & Rectangular shapes. Edgewise meters provide maximum performance in the smallest of space for vertical & horizontal mounting.

Salient Features

• EW 100 is uniquely styled & constructed to provide a slim landscape appearance to minimize panel space     requirements.
• Ruggedly designed with high stability moving coil movement.
• Constructed with transperant acrylic front with bezel moulded in black ABS.
• Can be installed in vertical or horizontal position.
