  • Features
  • This Noise Dose Meter meets the GB/T 15952 standard.
  • The Noise Dose Meter measure the frequency weighted noise exposures and peak sound levels simultaneously.
  • * Simple operation, including direct read–out of results.
  • * Eight built–in standard dose measurement setups : OSHA80, OSHA90, MSHA-80, MSHA-90, DOD, ACGIH, ISO85 and ISO90.
  • * Nine user – defined measurement setups.
  • * A single sound level meter (SLM) setup.
  • * A single sound level meter (SLM) setup.
  • * 50 dose (DATA) result stores.
  • * Download of setups from PC to the meter.
  • * Keypad lock protects meter against accidental operation.
  • * Timers support pre–selection of measurement time and duration.
  • * Use USB data output to connect with PC.
  • The meter is ideal for quick on–site surveys and for monitoring personal noise exposure in accordance with European ISO or USA OSHA, MSHA, DOD AND ACGIH standards.
  • The meter is two overlapping measurement ranges : 60 – 130 & 70 – 140dB, A & C RMS weightings, Linear & C Peak weightings, Fast & Slow time weightings, and energy exchange rates (Q) of 3, 4, 5 & 6. In dose measurement mode, it display % dose, % dose projected for an 8 hour period, peak level and measurement duration.
  • For countries that are subject to European Union regulations or the equivalent ISO standards,   the   meter   measure   the   daily   sound   exposure   level   (LAeq,8hr,Pa2h according to IEC 61252, which is identical with the L EX,8h   required by ISO 1999), while for USA OSHA/MSHA regulations they measure the Time Weighted Average level (TWA).
  • When used as a sound level meter it display sound level, time–averaged (L Aeq) sound level, peak and sound exposure level (SEL).
  • The meter is automatic run timing facilities controlled by the built–in clock and time–history recording capabilities. Sampling times can be specified between 1s and 1 hour, while storage is 120000 data points.
  • The meter is able to measure and save up to five specified Ln values (Statistical noise levels). Run duration, start and stop times preset, and other setting via the meter keys or software.
