What it is rented for

It is used to verify a sound level meter's calibration before measuring, both in the lab and in the field, for example at concerts, events, sound checks or venue measurements. According to the manufacturer, working at 1000 Hz lets you calibrate with any frequency weighting (LIN, A, B…) without a correction factor, and the 114 dB level makes calibration possible even with high background noise. If you would like to pair it with other gear from the SPL + RTA category in our catalogue, ask about compatibility when requesting a quote.
