## Summary description

Fnirsi FDM01 is a digital sound level meter designed to measure ambient noise between 30 and 130 dB. The compact device features a clear digital display for quick readings and is suitable for checking workplace noise, room acoustics, home appliances, or environmental sound levels. It provides an easy-to-use handheld solution for monitoring noise and ensuring compliance with recommended limits.

## Long description

The FNIRSI FDM01 is a compact digital sound level meter that measures ambient noise in the range of 30–130 dB and simultaneously monitors temperature and humidity. It features a sensitive 6 mm condenser microphone, a 2.3" VA color display with backlight, and a rechargeable 600 mAh lithium battery charged via USB-C. The device offers MIN/AVG/MAX display modes, FAST and SLOW dynamic response settings, a light alarm for threshold exceedance, and a HOLD function for value locking. The FDM01 is intended for use in offices, construction sites, transport, production rooms and public spaces where straightforward noise monitoring is required.
Advantages
The FDM01 provides accurate measurements with ±1.5 dB accuracy (calibrated at 94 dB, 1 kHz) across a frequency range of 31.5 Hz–8.5 kHz using A-weighting to match human ear sensitivity. Its 6 mm nickel-plated condenser microphone with silicone seals ensures high sensitivity and fast response while reducing interference from sudden volume spikes. The 2.3-inch VA display and clear dynamic scale (1 division = 2 dB) make readings easy to interpret, and the rechargeable battery with USB-C charging removes the need for disposable batteries. Durable ABS housing, silicone buttons and a soft wind shield improve reliability in field and industrial conditions.
Suitable for
Workplace noise checks and occupational hygiene assessments
Construction site and renovation noise monitoring
Measuring noise in production and industrial environments
Assessing room acoustics and appliance noise at home
Monitoring noise levels in public spaces and transport

How to use
Turn on the sound level meter and allow the microphone to stabilize for a short time before measurement. Select A-weighting and choose FAST or SLOW response depending on whether the situation requires rapid capture of changing levels (FAST) or a more stable averaged reading (SLOW). Point the microphone toward the noise source, keep the device steady, and observe MIN/AVG/MAX values as needed. Use the HOLD function to freeze a reading on the screen and enable the light alarm to notify when a preset threshold is exceeded. Recharge the internal battery using the supplied USB-C cable when low.
Usage recommendations
For repeatable results, measure at a consistent distance from the noise source and avoid placing the microphone too close to reflective surfaces. Use the SLOW mode for steady background noise and FAST mode for fluctuating or impulsive sounds. Store the device within the specified temperature and humidity ranges to maintain sensor accuracy.
