Key Features:
Class 2 Accuracy & Compliance
Certified according to IEC 61672‑1 Class 2, ensuring reliable and traceable
noise level measurements.
Wide Measuring Range: 30 dB to 130 dB
The meter operates across an extensive range—from quiet environments (30 dB) to
very high noise levels (130 dB)—suitable for industrial, environmental and
occupational noise monitoring. Auto & Manual Range Selection
Offers automatic measuring range by default, plus selectable manual ranges of
30‑90 dB, 50‑110 dB, and 70‑130 dB for flexible measurement setups.
Selectable A & C Frequency Weighting
User can switch between A‑weighting (closer to human hearing) and C‑weighting
(for lower frequency/peak sounds) modes.
Fast & Slow Time Weighting
Supports “Fast” response (125 ms) for transient/noisy environments and “Slow”
response (1 s) for general ambient measurements.
Built‑in Data Logger with PC Connectivity
Records up to 32,000 measured values in internal memory. Data logging
interval is configurable (from 1 second up to 24 hours) via micro‑USB
connection and included PC software. Ideal for long‑term monitoring and
detailed analysis.
MIN, MAX and HOLD Functions
Captures minimum, maximum and frozen values (HOLD) for noise events, making it
easier to identify peaks or sustained noise.
Portable, Field‑Ready Design
Lightweight (~307 g) and compact (approx. 248 × 90 × 35 mm), with USB recharge
capability and practical carry case. Suitable for field inspections,
environmental surveys and workplace audits.
Auto Power Off & Battery Indicator
To conserve battery life, the instrument features auto‑shutdown after approx.
3 minutes of inactivity (can be disabled when needed), plus low‑battery
indicator.
Versatile Applications & Professional‑Grade Data
Ideal for environmental noise assessments, occupational health & safety
audits, machine/plant noise monitoring, workplace compliance and consulting.
The data‐logging capability supports reporting and trend‑analysis.
