Acoustic Calibrator
Which Calibrator?
The most suitable calibrator from the range depends on your
application and the grade of sound level meter that you are
using:
The CEL120 Calibrator
The CEL120 calibrators have a simple button control. Inside the Calibrator is a MEMS microphone and digital feedback loop to maintain the acoustic pressure at the required level. An indicator shows if the sound level meter's microphone is not inserted in the cavity correctly, overcoming the most common cause of calibration failure.
The Class 1 version of the Calibrator (the CEL120/1) is dual-range, offering a 1kHz tone at both 94 and 114 dB. The Class 2 version (the CEL120/2) offers a 1kHz at a single level of 114 dB.
