Key Features:
Full personal noise-exposure monitoring (dosimeter mode):
Capable of measuring accumulated sound exposure over an 8-hour period — ideal
for workplace noise assessments, OSHA/IEC compliance, and long-term hearing
safety monitoring.
Dual-mode operation: Dosimeter + Sound Level Meter (SLM):
Use as a noise dosimeter for exposure surveys or as a traditional SPL meter —
giving flexibility for both occupational safety and general sound-level
measurements.
Adjustable measurement parameters: Criterion level
(80, 84, 85, or 90 dB), exchange rate (3, 4, 5 or 6 dB), and threshold level
(70–90 dB, 1 dB steps) are configurable — offering adaptability to various
regulatory standards and environments.
Comprehensive data logging & survey storage:
Stores up to 5 separate dosimeter surveys (with start/stop times, %Dose, TWA,
peak-flag data), and logs thousands of SPL readings when used as a sound meter
— enabling detailed exposure tracking and post-analysis.
PC Interface with RS-232 and data-analysis software
included: Enables configuration, data download, and analysis on PC — ideal
for workplace audits, regulatory compliance reporting, or long-term noise
studies.
Compact, wearable form factor with clip-on microphone:
Includes 1/2″ electret condenser microphone (with ~0.8 m / 2.6 ft cable), belt
clip and carrying case — convenient for personal noise exposure monitoring in
real working conditions.
Wide SPL measurement range (70–140 dBA) with fine
resolution (0.1 dB): Covers typical environmental and industrial noise
levels up to very loud conditions, with precise resolution for accurate
exposure assessment.
Peak-level detection & high-level alerting:
Device flags when sound exceeds 115 dB (high-level detector) and marks peaks
beyond 140 dB — useful for capturing dangerous noise events or sudden loud
exposures.
Lightweight and portable with long battery life:
Designed for field use — compact dimensions (≈ 106 × 64 × 34 mm) and powered by
4 × AAA batteries with ~34 hours runtime.
Standard-compliant for occupational & regulatory use:
Meets international standards including ANSI S1.25-1991 (Type 2), ISO-1999 and
BS 402 (1983) — suitable for professional noise surveys and regulatory
compliance.
