SPL Lab Next-Lab SPL Sensor

The SPL Lab Next-Lab SPL sound pressure sensor is intended for use together with data analysis units such as Next-LCD and Next-USB. The device has an internal ADC. The signal is digitized in the sensor and transmitted in digital form via the Lab bus. This prevents distortion and noise pollution of the measured signal during transmission. The signal can be transmitted via a cable over a distance of up to 10 meters. The Next-Lab SPL sensor has an extended amplitude range and a noise reduction system that enables measurements with an accuracy of up to 0.1 dB. Each copy of the device is thoroughly tested and calibrated.

The device is designed as a monoblock and consists of a high-frequency semiconductor sensor, ADC module and Lab-Bus interface. The device has a Lab-Bus port for data transmission. There are vacuum suction cups on the back for attaching the device to smooth surfaces such as glass. The housing of the device is made of impact-resistant plastic.
