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.

The generated sound pressure level is equal to 114 dB at 1000 Hz frequency. A LED signals the low battery condition.

Advantages:

• 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.
• The calibrator can be conveniently used both in laboratory and in the field. The 114 dB sound level allows performing calibrations even in high background noise environments.
• Its simplicity of use allows even unskilled staff to use it.

ISO 17025 calibration certificate according to IEC 60942 included.

The instrument is designed to deliver maximum performance in the analysis of acoustic phenomena with particular attention to regulations on environmental noise and building acoustics.

The integrating sound level meter is suitable for the following applications:

• environmental noise levels evaluation,
• noise monitoring with noise events capture and analysis,
• spectral analysis in octave bands from 16Hz to 16kHz,
• complete statistical analysis with percentile levels calculation from L₁ ad L₉₉
• measurement in working environments,
• selection of Personal Protective Equipment (methods SNR, HML and OBM),
• soundproofing and acoustic reclamation,
• production quality control,
• machine noise measurement,
• building and architectural acoustics (with “Reverberation time” option).

The HD2110L can be integrated with additional options to extend its application range when required; the firmware can be updated directly by the user by means of the Noise Studio program provided with the instrument.
