Features

This sound pressure level measurement amplifier is equipped with input terminals for various microphones.
Connecting the UC-34P or UC-35P (sold separately) enables low-level measurements, while connecting the UC-54 or UC-29 enables measurements in the high-frequency range, which cannot be detected by the human ear.
It can be used to check the operation of sensors that use small abnormal noises from machine parts or pressure in the high-frequency range.
The main unit is equipped with a large LCD to monitor the noise value in real time.
The unit is also equipped with a voltage output terminal, a communication interface and a terminal block on the rear panel, enabling control from a PC and linkage with external equipment via comparator output.
