dBELL 108

ASYS dBELL 108 Noise Monitor

A flexible tool for conducting occupational noise studies and assessing mitigation strategies, the ASYS dBELL 108 IIoT Multi-tool can be deployed as a personal exposure dosemeter, a handheld instrument or a remote monitor compatible with the ASYS dBELL IIoT ecosystem.

At the heart of the dBELL 108 is a calibrated, traceable sound level meter capable of measuring noise parameters required for workplace noise and personal exposure assessments, including LAeq, LCpk and %Dose.
Features
Usage modes:

◆ Personal exposure dosemeter: Shoulder mounted for general exposure or task specific assessments, for example drilling, boring, grinding etc.
◆ Handheld instrument: Conducting spot checks around the workplace environment.
◆ Remote monitor: For longer term studies on time-variable or intermittently noisy processes.

The dBELL 108 automatically connects to the ASYS dBELL 100 IIoT integrated gateway and area monitor via LoRaWAN®, a sub-g wireless technology ideally suited for long range and minimal power consumption.
