Castle GA216L is fully compliant with European and International standards. It is designed for use by industrial safety officers, safety managers and engineers, for compliance with the Control of Noise at Work regulations 2005. GA216L will provide all the necessary sound measurement information for completing noise at work risk assessments.Multiple file saving using on board Flash Memory. Dual channel measurements for Lp, Leq and Lmax. Simultaneous measurement of Lp, Leq, Lmax, Apeak or Cpeak or Zpeak, Lep,d, LAE, Dose, Dose \/ Hour, Pa2H, L10, L90 and L(user). Channel independent Frequency weighting selection ‘A’, ‘C’ or ‘Z’. Channel Independent Time weighting selection ‘Slow’, ‘Fast’ or ‘Impulse’. Sound pressure (Lp) to 0.1dB resolution. Integrated equivalent level (Leq) measurement. Personal sound exposure level (Lep,d). Single event sound exposure level (LAE). Percentile levels (L10, L90 and a user selectable level). Noise dose%, noise dose per hour%, pascal squared hours. Lmax - maximum Lp (rms) level. Apeak, Zpeak or Cpeak â€\" maximum Frequency weighted peak level. Elapsed time (running time hrs, min, sec).
