Mapping Capability – Quickly see the sites already surveyed, and where you need to survey next.

Increase Operational Efficiency – The Allegro AX’s Android OS and quad-core processor deliver fast performance. In addition, PCS Field Data Collector software works with your Allegro AX to streamline your survey workflow

Powerful Integrated Package – The Allegro AX features an integrated alphanumeric keyboard is ideal for rapid data entry, and a high-visibility screen you can view in direct sunlight. Your digital voltmeter (DVM) slots into the back of the Allegro AX, so you do not need to keep track of multiple components when you go out to the field.

Ultra-Rugged – Meeting IP68 and MIL-STD-810G ratings, the Allegro AX is designed to work in the most extreme conditions. So rain, extreme temperatures, or dust will not get in the way of your productivity.

DVM for the Cathodic Protection Industry  – The Allegro AX fully integrates with our digital voltmeter, DVM1110. The DVM 1110 is built on our patented technology to ensure highly accurate measurements in less-than-optimal cathodic protection environments
