Dual Level Acoustic Calibrator

Description

To ensure your noise measurements are legally compliant with Noise Regulations you MUST field calibrate your sound level meter before and after taking your measurements; most noise-related regulations stipulate that the noise meter or noise dosemeter is calibrated before each acoustic calibration session and checked again before turning the instrument off.  In fact, noise measurements made for ‘official’ use, such as industrial health & safety or environmental monitoring, are not valid unless correct calibration procedures have been followed.

Our dual-level acoustic calibrators are suitable for the field and laboratory calibration of sound level meters, noise dosimeters, and other noise measurement instruments.

The calibrator is simple to operate and meets the requirements of the latest IEC 60942:2017 standard for acoustic calibrators with performance to Class 1 or Class 2 and features both 94dB and 114dB at 1kHz sound pressure level output in one single instrument.

It’s ideal for use with a variety of noise dosimeters, where 94dB or 114dB can be used in preference.
