The Brüel & Kjær 4448 personal noise dose meter assesses noise exposure in the workplace, informing users of the level of hearing protection required. It is available to rent from TechRentals.
The cable-free meter simultaneously measures all relevant parameters required by Noise at Work standards. It can be used in hazardous environments such as mining and petrochemical facilities, where only certified equipment can be legally used.
It features 180 h logging storage, including LAeq and LZpeak. It also has an auto-calibration function and a rechargeable battery with an operation time of 28 h.
An LCD display shows battery and memory status and a dB alarm LED indicates dangerous noise conditions. A kit of three includes a Type I calibrator.
