Cirrus research CR110A Heavy-Duty Personal Noise Dosimeter (70dB(A) ~ 130dB(A) RMS, 120dB(C) ~ 140dB(C) Peak)

The CR:110A doseBadge Personal Noise Dosemeter and the RC:110A Reader Unit have

been designed to meet the requirements of IEC 61252:1993 Personal Sound Exposure

Meters and the ANSI S1.25:1991 Personal Noise Dosemeters. The CR:110A doseBadge

and the RC:110A Reader unit must be used as a combination to ensure compliance with

these standards.
