FNIRSI FDM-02 Digital sound level meter

The FNIRSI FDM-02 is a digital sound level meter with a colour display and a condenser microphone, designed for accurate measurement of noise levels in a range of working environments. It supports A and C frequency weighting as well as FAST and SLOW response modes, so you can adapt the measurement to the type of noise you are assessing.

The condenser microphone provides high sensitivity and stable readings. Measured values are shown in real time on a clear, easy-to-read display. Data logging produces graphs of sound level changes, making fluctuations over a period easy to spot and results simple to compare without handwritten notes.

The meter can also monitor ambient temperature and humidity alongside noise readings. The ergonomic button layout lets you switch between operating modes and adjust settings quickly, whether you are working in the field or indoors. The package includes the sound level meter, a USB cable and a carrying bag.
