FNIRSI FDM-02: The Ultimate 3-in-1 Digital Sound Level Meter

Tired of guessing noise levels? Take control of your acoustic environment with the FNIRSI FDM-02 High-Precision Digital Sound Level Meter. Whether you're a professional ensuring workplace safety, a homeowner identifying noise pollution, or an audio enthusiast perfecting your setup, this device delivers accurate, real-time data with unparalleled ease.

It’s more than just a noise meter; it's a complete environmental analysis tool that also measures temperature and humidity, all displayed on a brilliant 2.0-inch color screen.

Key Features:

All-in-One Environmental Analysis

Why juggle multiple devices? The FDM-02 seamlessly integrates three sensors into one handheld unit.

• Noise Meter: Accurately measures sound levels from a quiet whisper (30dB) to a loud concert (130dB).
• Thermometer: Monitor ambient temperature to understand your full environmental conditions.
• Hygrometer: Keep track of humidity levels, crucial for comfort, health, and equipment preservation.

Professional-Grade A/C Dual-Weighting

Measure sound like a pro. The FDM-02 offers two professional weighting modes for diverse environments:

• A-Weighting: Simulates human ear perception, perfect for measuring environmental and domestic noise (e.g., traffic, conversations, neighbor noise).
• C-Weighting: Captures low-frequency sounds with greater accuracy, ideal for measuring mechanical and industrial noise from machinery, engines, and equipment.

Instant & Stable Readings: Fast/Slow Mode

Adapt to any situation with one-click switching between two measurement speeds:

• FAST Mode (125ms): Captures transient noise peaks and rapid sound fluctuations with a super-quick response time.
• SLOW Mode (1 second): Provides a stable, averaged reading of fluctuating noise levels, making it easier to record a general sound level.

Visualize The Noise with Curve Recording

Don't just see a number—see the story. Switch to the curve recording mode to get a real-time graph of noise level changes over time. This visual data makes it incredibly easy to track trends, identify peak noise events, and understand the soundscape of any location.
