Sound Wave Sensor
1Sound wave sensor can display the sound
2intensity and study sound waveform
3High precision physics

ZJKY 1030 Sound Wave Sensor(chemistry lab apparatus)
Level 1(soundwave measurement):40dB~120dB:resolution0.1 Db;
Level 2(waveform measurement):-2.5V~+2.5V(measurement frequency range 10Hz~400Hz);Resolution1Hz.

Application: The soundwave sensor acts as a speaker (microphone), used to receive sound waves, show the vibration image of the sound, but cannot measure the intensity of the noise . 

Description:  Its sensitive apparatus is placed in the front of the sensor.Measured with the unit dB, the displayed data is the sound intensity value at the position of the sensitive apparatus.
