The HD2024 sound level calibrator is a portable, battery operated sound source, suitable for sound level meters (portable and laboratory) and acoustic stations.
It allows calibrating 1/2” (1/4” with HD2020AD4 adapter) microphones with mechanical dimensions compliant with IEC 61094-1 and IEC 61094-4.
The generated sound pressure level is equal to 94 dB at 1000 Hz frequency. A LED signals the low battery condition.
Advantages of the HD2024 calibrator:
The 1000 Hz frequency allows calibrating sound level meters with any frequency weighting (LIN, A, B, …), without applying any correction factor.
The generated sound pressure level is indipendent of atmospheric pressure: you don’t need to adjust the value according to static pressure over a wide range of values.
Its simplicity of use allows even unskilled staff to use it.
It includes ISO17025 Calibration Certificate.
