Original doseBadge (CR:110A)
CurrentCompact shoulder-mounted personal noise dosimeter with no cables, controls or display, measuring A-weighted exposure and C-weighted peak on two channels and read out through the RC:110A Reader Unit over an infrared link. An intrinsically safe version (CR:110AIS) carries ATEX, UKEX, IECEx, FM, MSHA and SIMTARS certification for use in explosive atmospheres and mines.
