Key Features:
Class 2 high-accuracy sound measurements: Complies
with international standards (IEC 61672‑1, IEC 60651, IEC 60804, ANSI S1.4‑1983
and ANSI S1.43‑1997) — suitable for regulatory compliance, workplace noise
assessments, environmental noise monitoring, and professional acoustic
analysis.
Wide measurement range (25 – 136 dB(A)) & broad
frequency response (20 Hz – 12.5 kHz): Covers quiet ambient noise to very
loud environments, capturing a full spectrum of sound levels.
Flexible frequency & time weightings: Supports A,
B, C and Z frequency weightings, and Fast (125 ms), Slow (1 s), Impulse (35 ms)
time-weightings — allowing accurate measurement of varying noise types
(constant, impulsive, or fluctuating).
Octave-band analysis (1/1 octave standard; optional 1/3
octave upgrade): Enables detailed frequency analysis for acoustic studies,
noise source identification, and compliance with noise regulations.
Integrated data-logging with adjustable intervals (1
second … 24 hours): Automatically records and stores long-term noise data
for trend analysis, environmental monitoring, or compliance reporting.
Large backlit LCD with real-time numerical and graphical
display: Offers immediate visual feedback of SPL levels and trends — handy
for on-the-spot assessments.
Multiple measurement functions & statistics: Includes
SPL, equivalent continuous sound level (Leq), LXY (instant SPL),
maximum/minimum, peak hold, statistical percentiles (1 %–99 %) — giving
comprehensive insight into noise characteristics.
Low self-noise and high-resolution 24-bit AD converter
with 48 kHz sampling: Ensures stable, accurate, and low-noise recordings —
important for precise acoustic measurements and data integrity.
Flexible power & data transfer options (USB, RS-232,
micro-SD): Allows connection to PC for easy data download and analysis, or
storing data on 4 GB microSD memory — convenient for field operations.
Portable, professional-grade design: Handheld meter
with included microphone, windscreen, power options (batteries or adapter) and
carrying case — ideal for fieldwork in construction sites, traffic noise
studies, workplace safety audits, airports, environmental assessments, etc.
