Firefly

Portable Real-time Data Acquisition Unit

The HGL Firefly is a complete portable data acquisition, monitoring, and analysis solution—purpose-built for engineers who need performance on the move.

Combining a powerful tablet-class computer with eight independent 24-bit analog input channels, the Firefly delivers high-resolution data acquisition in a compact, all-in-one package. Housed in a rugged milled aluminum chassis, it’s engineered to withstand the demands of industrial environments, providing durability and protection during field testing.

The unit features a 10.4″ capacitive touchscreen for intuitive control and data visualization, along with a high-capacity 90 Wh internal rechargeable battery for extended operation away from power sources.

By default, the Firefly includes IEPE (1408) signal conditioning, supporting AC/DC coupling and selectable gain options (1x, 10x, 100x). A range of additional signal conditioning modules is also available, ensuring compatibility with virtually all industry-standard input types.

Whether you’re capturing vibration, strain, pressure, or voltage, the Firefly provides a flexible, field-ready platform that simplifies complex measurements—wherever your work takes you.
