Use the digital sound level meter C.A 832 for the proper measurement of sound levels according to IEC 651 Type 2. The professional and private application range is diverse: measuring sound levels in factories, schools, offices, airports, studios, lecture halls, etc. The C.A 832 allows for the measurement of sound levels from 37 to 130 dB across 3 measurement ranges. It features 2 weighting curves, A and C, which take into account the sensitivity of the human ear depending on frequency. The modes F (fast response time) and S (slow response time) facilitate this.
