Product 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.This Noise Dose Meter meets the GB/T 15952 standard.
【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.
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.
