I. Specifications of Sound calibrator Larson Davis CAL200

1/2" MICROPHONES - IEC 60942 CLASS 1 CALIBRATOR

Precision sound level calibrator Larson Davis CAL200 is a battery operated precision microphone calibrator used for the calibration of sound level meters and other sound measurement equipment with 1/2" microphones. It can provide an output level of either 94.0 or 114.0 dB (switch-selectable) at a frequency of 1 kHz. Adaptors for 1⁄8", ¼", and 3⁄8" microphones are available as optional accessories.

The Larson Davis CAL200 features a stable sound pressure independent of the battery condition. In addition, the Larson Davis CAL200 will turn off automatically to preserve battery and guarantee a stable output.

In addition to precision acoustic calibrators, factory calibration services for Larson Davis products are available through the CAL+ program. CAL+ service is provided with all Larson Davis calibrations and includes a complete multi-point factory test, free firmware upgrade to the latest version where applicable, labor warranty extended for one year[1], worn consumables replaced at no charge[2], and more. Contact us for details.
