Personal Sound Level Meter DB22-600DOSE

Number DB22-600DOSE

Brand Duty-free

Model DB22-600DOSE

【Product Applications】

A personal noise dose meter is a testing device used to evaluate the noise conditions in the workplace by measuring cumulative noise exposure. With this test data, the company can ensure that relevant noise regulations are followed or decide whether to take action.

Established noise reduction measures to prevent acoustic injury and hearing loss caused by noise among staff. This noise dosimeter complies with the GB/T 15952 standard.

【Product Features】

The noise dosimeter simultaneously measures frequency-weighted noise exposure and peak sound levels.

Simple operation, including direct result reading.

* Eight built-in standard dose measurement settings: OSHA80, OSHA90,

MSHA-80, MSHA-90, DOD, ACGIH, ISO 85, and ISO 90.

Nine user-defined measurement settings.

50-dose (data) results storage.

Download settings from PC to dashboard.

The keyboard lock protects the instrument from accidental operation.

Timer supports pre-selected measurement and duration settings.

Features USB data cable output for communication with PC.

* Single-channel sound level meter (SLM) setup. This instrument has two overlapping measurement ranges: 60–130&70–140 dB, with A and C root mean square weighting, linear and C peak weighting, fast and slow time weighting, and energy exchange rates (Q) 3, 4, 5, and 6. In the dose measurement mode, it displays dose %, predicted dose % over 8 hours, peak level, and measurement duration. For countries adhering to EU regulations or equivalent ISO standards, the meter measures daily exposure sound levels (IEC 61252 standard's LAeq, 8hr, pa2h, equivalent to ISO 1999's L EX,8h); for U.S. OSHA/MSHA regulations, they measure time-weighted average (TWA). When displayed as a sound level meter, it shows time-weighted average sound level (-LAeq) and peak sound exposure level (SEL). The meter operates automatically with a timer controlled by an internal clock and time-history memory. Sampling time can be set between 1 second and 1 hour, with 120,000 data points stored. The instrument can measure and save up to five specified LN values (statistical noise level). Operation time, preset start and stop times, and other settings can be set via the meter's keys or software.
