Easy-to-use acoustic calibrator for sound meters

Acoustic calibrator [Models 105 and 106]

Quickly check the accuracy of your sound meter. Acoustic calibrators allow you to set the sensitivity of any noise meter with a 0.5-inch microphone (0.25-inch adapter also available). Pulsar’s calibrators meet IEC 60942: 2003, giving you confidence in their reliability and accuracy. Available as class 1 or class 2.

Acoustic calibrator ensures legally compliant noise measurements

Noise regulations require you to calibrate your noise meters before and after taking sound measurements. The acoustic calibrator from Pulsar Instruments makes this process quick and easy.

The calibrator fits over a sound meter microphone and emits an industry-standard, 1-kilohertz tone at 94 decibels. The calibrator fits any noise meter with a 0.5-inch microphone, and a 0.25-inch adapter is also available. Internal sensors correct for temperature, humidity and barometric pressure, which keeps the calibrator accurate in changing conditions.

Choose class 1 (model 105) or class 2 (model 106) depending on your sound meter. Both sound meters meet the latest international standards (IEC 60942:2003). Use them to ensure your sound meters meet legal requirements for industrial or environmental noise assessments.
