DUO is innovative and unique on the market of sound level meters dedicated to environmental noise measurement. The DUO introduces a new measurement concept, just what you’ve been waiting for: the all-in-one instrument.

A classical sound level meter for use “on site”
DUO is devoted to classic hand-held sound level meter measurements on site, either using the built-in keyboard and screen or dBDUO software interface on a wireless commercial remote control, fixed or not to the body of the instrument with the integrated magnet.

A short, medium or long-term noise monitoring station
Based on its all-weather design, DUO is also perfectly suited to indoor and outdoor noise monitoring. Its operating battery lifetime allows for more than 60 hours of measurements without external power supply.
• Wireless connections (Wi-Fi and 3G) to DUO allow for remote access to the measurements in progress and selective retrieval of stored data avoiding physical presence of the operator in the field.
• DUO’s “all in one” unique design allows for extremely easy and fast transport and installation.
• DUO’s on-board periodical self-check of the entire measurement chain guarantees the reliability of the measurement results.

With the DUO, you get access to unrivalled technical performances.
