Noise Level Meter Calibrator Tool

Product Description:

The noise level meter calibrator tool features dual sound levels and multi-frequency sound signals. It is suitable for calibrating noise measuring instruments such as microphones and sound level meters with nominal diameters of 23.77 mm, 12.7 mm, and 6.35 mm. In addition to calibrating the overall sensitivity of noise measuring instruments, it can roughly check the linearity of the instrument levels and the errors of the level range controller. Utilizing a microcontroller as its core, it employs digital synthesis technology to generate precise and stable sine signals. With a built-in reference microphone and sound feedback technology, the generated sound pressure level exhibits excellent temperature stability and static pressure stability.
