Field calibration is essential for accurate and legally compliant noise measurements. An acoustic calibrator allows you to check your sound level meter or noise dosimeter before and after each measurement, ensuring your results comply with occupational noise regulations.

Standard 1 kHz Reference Tone

The Model 105 (Class 1) and Model 106 (Class 2) acoustic calibrators produce a standardised 1 kHz tone at 94 dB. Built-in sensors automatically correct for temperature, humidity, barometric pressure and battery condition, helping maintain accuracy in a variety of conditions.

Available as a Class 1 or Class 2 Calibrator

Both models are easy to operate and fully comply with IEC 60942:2003. The Model 105 is suitable for Class 1 sound level meters, while the Model 106 is designed for Class 2 instruments typically used in occupational noise assessments.

Durable and Easy to Use

Each calibrator is compact, durable and easy to use, with a long-life 9-volt battery and an automatic power-off feature to prolong battery life.

The Acoustic Calibrator is available as a Class 1 or Class 2 model, compliant with IEC 60942:2003. For accurate calibration, the calibrator should match the Class of the sound level meter being calibrated.

The Acoustic Calibrator includes a standard 1-year warranty, which can be extended to 10 years when the instrument is returned to Pulsar Instruments for annual calibration.

The section below outlines the basic operation of the Acoustic Calibrator. For full instructions on calibrating specific equipment, please refer to the relevant equipment user manual.

Using the Acoustic Calibrator

Carefully fit the calibrator over the microphone capsule, ensuring a firm connection. When switched on, the Acoustic Calibrator emits a 1 kHz tone for acoustic field calibration. Press the power button once to produce a 94 dB tone, or press it a second time to switch off the device.
