Get Digital Accuracy with an Analog Footprint
The DW Series is a cost-effective solution to retrofitting an analog
panel cutout with a digital meter.
•
The DW is easy-reading with large display and wider viewing angles
•
No additional wires makes installation faster and easier
•
Automatic polarity indication
•
Custom nomenclature optional
