Class 2 Acoustic Dosimeter DC112d

Class 2 acoustic dosimeter

The DC112d is a high-performance dosimeter, an ideal instrument for noise measurement according to Directive 2003/10/EC, which adapts regulations on the protection of health and safety of workers against risks related to noise exposure; in Spain, transposed by RD 286/2006. The DC112d dosimeter allows simultaneous measurement of all parameters necessary to assess worker noise exposure with and without hearing protectors, by SNR and HML methods, also by the octave band method acquiring the option for octave band analysis. The DC112d dosimeter measures the equivalent level (Leq) with A and C weighting [LAt, LCt] (SNR and HML method). And of course, also the peak level with C weighting [LCpeak].

- Simultaneous measurement of all parameters

- Calculation of projected dose

- Noise measurement according to Directive 2003/10/EC / R.D. 286/2006

- Large memory capacity

- USB discharge and power supply port

- Complies with current regulations on LEGAL METROLOGY (ITC 2845 / 2007)
