The Casella dBadge2 Noise Dosimeter keeps all the great attributes of the original dBadge but adds incredible features you won’t want to do without!  When Casella CEL introduced the revolutionary micro-sized dBadge cable-free, shoulder-mounted noise dosimeter to Industrial Hygienists and Safety professionals worldwide in 2006, it revolutionized personal noise exposure sampling in a significant way. Gone were all of the hassles and safety concerns of cable-mounted microphones – yet all the essential features of ‘traditional’ noise dosimeters (LCD data display, on-board control keys, IS approvals, ‘multiple metrics’ capture and secure data storage) were retained. No other dosimeter then could claim these attributes and today we are proud to announce the arrival of the revolutionary Casella dBadge2 Noise Dosimeter.

Imagine being able to view noise exposure data from multiple workers, remotely right on your cellphone or tablet. Now you can access each ANSI/IEC standards compliant dBadge2 noise dosimeter directly from your HHD using the built-in Bluetooth®4.0 connection and the Casella Airwave App! What this means is you no longer have to interrupt the worker and their work to ensure your noise exposure data are being gathered as expected. You can see overall exposure metrics, including averages, max and peak; instrument status, and all without even being in sight of a worker under test. You can start, stop and pause a test as many times as you like, remotely, without ever bothering the worker again. If you choose, you can email or text summary of noise exposure results right from your tablet or smartphone directly to other people such as plant managers or supervisors.

Beyond this ground-breaking advancement in noise exposure sampling methodology, the Casella dBadge2 noise dosimeter and Casella dBadge2 Plus noise dosimeter and the Casella dBadge2 Pro noise dosimeter models also offers you capabilities rarely found in personal noise dosimeters including how to select proper hearing protection, or determine whether a process can be made safer in a cost-effective manner through the use of Octave Band measurement data (Pro model). Also included is a built-in motion sensor which ensures that the analyzer is being worn.

All Casella dBadge2 noise dosimeter models have kept the simple 2-button operation and one-touch calibration features that are so popular. The case itself is more robust and better sealed against the elements; the display screen is much larger and has a brilliant color OLED display; and the new improved windscreen design is much less susceptible to inadvertent damage thanks to a much larger grip ring and simpler attachment method. Even the attachment clips have been improved to grip more tightly on the widest possible assortment of clothing types in a way that limits stress to the clip itself, extending its useful life indefinitely. Of course, the dBadge2 noise dosimeter still captures every bit of data you’ll ever need from every single test, to meet virtually any existing, proposed or even hypothetical standard in use anywhere. And, it downloads to a new improved version of Insight software for simple and custom tailored report generation and archiving.
