I. Specifications of Handheld sound calibrator Larson Davis CAL150

IEC 60942 CLASS 2 CALIBRATOR

Handheld sound level calibrator Larson Davis CAL150 is a battery operated precision microphone calibrator used for the calibration of sound level meters and other sound measurement equipment.

It can provide an output level of either 94.0 or 114.0 dB (switch-selectable) at a frequency of 1 kHz. CAL150 includes an adaptor for 3⁄8" microphones. A 1/4" adaptor is also available as an optional accessory.

The Larson Davis CAL150 features a stable sound pressure independent of the battery condition. In addition, the Larson Davis CAL150 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. Please Contact us for details.
