Allegro 3 Rugged Handheld

The Juniper Systems Allegro 3 rugged handheld has been designed for data-intensive applications even in the harshest of conditions.



The Allegro 3 rugged handheld from Juniper Systems has a lightning-fast processor, powerful Android operating system and full alphanumeric keypad. Although it was designed with the same time-tested ergonomics, ruggedness, and display of the successful Allegro 2, the Allegro 3 is the most powerful Allegro yet.

The ARM Cortex processor is lightning-fast and the Android operating system makes the Allegro 3 a modern-day workhorse. The upgraded processor provides a 20% speed increase when compared to the Allegro 2, making it the ideal solution for data-intensive applications… even in the harshest of conditions.

The Allegro 3 has an IP68 rating, thereby exceeded military equipment standards. This means it is dustproof, waterproof, and shockproof and can operate in temperatures ranging from -30 °C to 70 °C. It can also perform in hours of pouring rain and survive multiple 4-foot drops on concrete.

Long workdays are made easier with the ergonomic design of the Allegro 3. It features a 4.2-inch high-visibility capacitive display for working in sunlight, 20-hour battery with Overtime Technology, and backlit alphanumeric keypad for rapid data entry.
