FFT frequency meter noise meter / Model number M22H-7351A
By equipping it with a wide range of functions not found in conventional measuring instruments, it addresses product development, quality control, noise monitoring, architectural acoustics, and occupational health and safety.
Measurement data and waveform recordings (WAVE files) can be recorded on an SD card and transferred to a PC. The virtual keyboard function of the PC control and projector software allows you to control the M22H-7351A with the PC mouse. Additionally, it is equipped with standard features such as data logging, RT60 reverberation time, polarity, delay, THD+N measurement, and voice note recording.
