Next-Lab SPL Sensor (Wide Band Edition)

Usually ships in 24 - 48 hours.


The wide range sound pressure sensor is designed for joint use with Spl-Lab devices that have a Lab-Bus expansion port. The device has a built-in ADC, that is, the signal is digitized inside the sensor and transmitted in digital form via the Lab-Bus. This prevents distortion and noise of the measured signal during transmission. The signal can be transmitted over a cable up to a distance of 10 meters. Next-Lab SPL Sensor(Wide Band Edition) has an extended amplitude and frequency range, which allows measurements over the entire audible range up to 20,000 Hz with an accuracy of 0.1 dB. Each copy is carefully checked and calibrated.


The device is performed as a monoblock, combining the high-frequency solid-state sensor, ADC module and Lab-Bus interface. The device has one Lab-Bus port for transmitting data. At the back cover, there are vacuum suction cups for affixing the device onto any smooth surface such as glass for example. The case of the device is made of shockproof plastic material.
