Casella

Casella makes occupational noise measurement instruments. TSA lists dBadge2 noise dosimeter kits in standard, Plus and Pro versions, with a 55 to 140.3 dB range, audio recording on some models, real-time octave band analysis on the Pro, and intrinsically safe versions for hazardous areas. Match the version to your reporting needs and to the classification of the area where the dosimeter will be worn.
