Key Features:
Complies with international standards (IEC 61672:2013
Class 1), offering high‑precision noise level measurement.
Wide measuring range: 20 dB to 142 dB (peak up to
~145 dB), ensuring suitability for very quiet to very loud environments.
Broad frequency response: 10 Hz to 20 kHz ±1 dB,
capturing low‑frequency and high‑frequency components beyond typical meters.
High accuracy: ±0.7 dB (reference), delivering reliable and
trustworthy sound measurements.
Real‑time 1/3‑octave band analyzer built in: allows detailed
frequency band analysis (center frequencies from ~12.5 Hz up to 20 kHz) to
identify noise sources by frequency.
Multiple weighting and time settings: supports A, C, Z
frequency weighting in parallel; time weighting options including FAST (F),
SLOW (S), and IMPULSE (I) for versatile measurement profiles.
Integrated GPS positioning: enables logging of measurement
location (latitude/longitude) alongside noise data, useful for environmental
surveys and regulatory compliance.
Large‑colour display with high resolution: e.g., 240×320
resolution colour screen, high readability and intuitive menu interface.
Data logging and memory: built‑in storage (e.g., 32 MB flash
memory) plus PC/USB connectivity for exporting data and analysis.
Long‑term monitoring support: with measurement modes such as
“Once”, “24 h automatic monitoring” and interval/limit triggers, making it
suitable for environmental and occupational noise monitoring.
Robust build and portability: compact size
(~260 × 80 × 30 mm) and light weight (~0.35 kg including batteries), ready for
field use.
Optional add‑ons: features or modules that can be
enabled/added such as audio recording in WAV format, Bluetooth/RS‑232
interface, thermal/dot‑matrix printing and user‑defined weighting curves.
