The meter features autocalibration function and 180 h logging storage with LAeq and LZpeak. An LCD allows users to review instrument, battery and memory statuses and the rechargeable battery gives an operation time of 28 h.
Other standard features include a dB alarm LED and cable-free operation. A kit of three meters includes a Type 1 calibrator.
