The doseBadge Noise Dosimeter is a high performance noise measurement instrument that meets the standards required by the Noise at Work Regulations as well as other International occupational noise regulations.
The specifications and performance information for the doseBadge are shown below.
Applicable Standards
CR:110A doseBadge
IEC 61252:1993 Personal Sound Exposure Meters
ANSI S1.25:1991 Personal Noise Dosemeters Class Designation 2AS-90/80-5
RC:110A Reader Unit
Internal Acoustic Calibrator to IEC 60942:2003 Class 2
Measurement Range
(Typical) 70dB(A) to 130dB(A) RMS
120dB(C) to 140dB(C) Peak
Measurement Functions
The CR:110A doseBadge and RC:110A Reader Unit support Dual Channel measurements.
The information provided by the doseBadge consists of the Overall Measurement Data, Channel 1 measurement data and Channel 2 measurement data.
If the doseBadge is configured with Channel 1 and Channel 2 having identical parameters, the dBLink3 software will only display Channel 1.
