01dB CUBE Smart Noise Monitoring

Overview

CUBE is the new noise monitoring terminal from 01dB, at the cutting edge of innovation. Designed to meet the needs of all kinds of applications, CUBE can be adapted to suit every situation: portable in a carrying case, stationary in a fixed unit, and compatible with 01dB WebMonitoring services.

It stays connected around the clock, operating continuously and responding simultaneously to your requirements: acoustic and meteorological measurements, automatic publication of data, communication of alarms, as well as parameter configuration changes, real-time display or listening option, etc.

With an IEC 61672 class 1 certification, CUBE guarantees flawless metrological quality in every situation. In addition, to provide you with information about the measurements, CUBE incorporates the most sophisticated event-detection filter system. As a result, various actions are triggered automatically, including coding, signal recording, notification by text messaging, and start-up of warning lights.

CUBE is part of a unique "ecosystem" focused on improving your productivity. You will appreciate its simplicity of use, its degree of remote controllability and the power of its processing software. By combining CUBE with 01dB WebMonitoring services, measurements can be accessed via a customized Web interface. CUBE is the ultimate noise monitoring terminal.
