For acoustic experiments, for example, for measuring the frequencies, amplitudes and speed of sound waves, and investigating sound spectra by means of fast Fourier analysis. The microphone capsule is very small and therefore especially suitable for interference measurements.For direct connection to the digital counter (U21000), or LabPro? (U44000) via the adapter (U20604), or an oscilloscope or multimeter via the battery box (U20602).Enclosed is a metal tube, including a stainless steel rod with a retention clamp and a 1-m long connecting lead with a 6-pole DIN plug. Frequency range: 20 Hz ? 20 kHz.Supply voltage: 5-8 V DCStainless steel rod: 100 x 10 mm ?Dimensions: 105 x 30 mm
