The calibration frequency for the class II sound level calibrator is 1000 Hz and is sinusoidal in shape. Compared to other calibrators, this calibrator has three adjustable sound pressure levels: 94 dB, 104 dB, and 114 dB. This means that an additional sound pressure level of 104 dB is available. With an accuracy of ± 0.4 dB, the class II sound calibrator is particularly reliable.
With a 50-hour battery life, the calibrator has an especially long operating time with automatic shutdown after 20 minutes of inactivity.
