Description
- Applications---The personal noise dose meter is test equipment to evaluate the noise condition of working environment by measuring the accumulated noise exposure.With this test data, company can ensure the related noise regulation is followed or decide whether or not to apply certain noise reduction action to avoid the acoustic trauma and noise-induced hearing loss occurs to the working personnel.
- Principle---DOSE is a parameter used to quantify noise exposure measured in a period,If the noise level was say 93dBA, 3dB higher, a 100% DOSE would be accumulated in only 4 hours, The above example is for a dose meter with 3dB Exchange Rate, where a 3dB increase in sound level corresponds to a doubling energy. A dose meter with 5dB Exchange Rate is also, available where the sound must increase by 5dB to double the dose as required to meet noise legislation in some countries.
- Features---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.* 50 dose (DATA) result stores. * Download of setups from PC to the meter. * Use RS-232 data output to connect with PC.
- Description---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 standardsThe meter is able to measure and save up to five specified Ln values.
- Specifications---Clock:Real–time clock with calendar Memory:Results from 50 measurements can be stored for later viewing and download Measurement Control:Measurement Duration : May be set to 5, 10, 15, or 30 minutes or 1, 2, 4, 8, 10, 12, or 24 hours Timers:Up to 16 timers(automatic start and stop)can be set(maximum up to one month ahead of measurement time) Timer Controlled Started / Stop:Set up from the PC software or meter keypad Logging:All measurement parameters values.
