The FNIRSI FDM-02 is a versatile 3-in-1 digital sound level meter designed for precise measurement of noise levels, ambient temperature, and humidity.
Key Features
- Accurately measures noise level, ambient temperature, and humidity.
- Features a bright 2.0-inch color TFT display for clear real-time data visualization.
- Offers professional dual A/C weighting for diverse environments. A-weighting simulates human ear perception for household and environmental noise, while C-weighting accurately captures low-frequency sounds for industrial applications.
- Supports Fast (125 ms) and Slow (1 s) time weighting modes, ideal for capturing transient peaks or stable average readings.
- Includes a curve recording mode to visualize noise changes over time.
- Compact, portable design powered by a 1500 mAh rechargeable lithium battery.
Applications
This device is suitable for a range of applications, including workplace safety monitoring, identifying noise pollution in residential areas, and assisting audio enthusiasts in optimizing their setups.
