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
This personal noise dose meter evaluates workplace noise conditions by measuring accumulated noise exposure. The data helps companies comply with noise regulations and implement necessary noise reduction measures to prevent acoustic trauma and noise-induced hearing loss among personnel.
The meter quantifies noise exposure using the DOSE parameter, representing % noise exposure relative to 90dBA for 8 hours (100% DOSE). Different criteria are available to meet international legislation requirements. The device supports both 3dB and 5dB exchange rates, where sound level increases correspond to dose doubling at different rates.
