The FNIRSI FDM01 is a compact decibel meter that combines a 30-130 dB noise measurement function with simultaneous temperature and humidity monitoring. The device has a sensitive condenser microphone, a 2.3-inch VA color display with backlight and a rechargeable lithium battery (600 mAh) that can be charged via USB-C. Thanks to its fast response time, MIN/AVG/MAX measurement modes, light signaling and two detection modes (FAST/SLOW), the FDM01 FNIRSI will be useful in the office, construction site, transport, production facilities and public spaces.

Precise measurement microphone

The 6 mm condenser microphone used is characterized by high sensitivity and fast response time. The use of nickel-plated steel, three-layer conductive structure and silicone seals effectively isolates interference and ensures reliable results even with sudden volume jumps. The FNIRSI FDM01 decibel meter allows you to choose between fast (1 sec.) and slow (1.25 sec.) measurement modes. This allows you to choose how to record data in dynamically changing conditions or to obtain a more stable result for fixed noise sources.

A-weighted measurement mode

The device uses A-weighted characteristic, which corresponds to the sensitivity of the human ear to different frequencies. The measurement is performed in the range of 31.5 Hz to 8.5 kHz, which allows you to reliably assess the ambient noise level according to standards.

Light signal and value lock

The FDM01 indicates with a red warning light when the set sound threshold is exceeded. It is also possible to display only the minimum, average or maximum value, making it easier to document the results. The “HOLD” function allows you to keep the current reading on the screen.

Easy-to-read display and durable housing

The 2.3-inch VA display clearly displays all data even in bright environments. ABS plastic housing and silicone buttons increase the durability of the device in outdoor and industrial conditions. Soft windscreen design reduces the impact of ambient noise on the measurement. 600 mAh lithium battery eliminates the need for batteries. The device is charged via USB-C port, which simplifies operation and reduces operating costs.
