Wireless Sound Level Sensor

Bluetooth | USB | Huge Battery Life | Independent Logging

This sensor accurately measures sound pressure level in decibels (dB) or examining the frequency content of sound in waveform (mV). The A filter used in the dBA range measures mid-range frequencies to approximate the normal human ear in the range and intensity that it ‘hears’ sounds. The C filter (dBC range) suits low and high frequency sound levels.

Wireless Sound Level Sensor
Reliable and durable, designed for the classroom

All our sensors come with 5 years warranty and lifetime support, we ensure your investment gives you complete peace of mind.
