Sound Level Meter SL-824 is a digital multi-function Sound Level Meter designed to measure sound pressure level and are commonly used in noise pollution studies for the quantification of almost any noise, but especially for industrial and environmental.
The device meets the measurement requirements of Safety Engineers, Health, Industrial Safety Offices and Sound Quality control in various environment. It features Bar-graph Indicating & Max Value Holding, built-in condenser mic and digital display. It accurately measures the sound level of just about anything from sound of level of environment to mechanic, vehicle, ship, loudness of computer fans and other noise with ± 1.5 dB accuracy. It has the following advantages: 30~130dB range, with A/C weighting, fast/slow response, equipped with Max mode that captures and hold the maximum noise level, provides a windscreen for filter-out unwanted signals and a 9V battery with no extra charge. In almost all countries, the use of A-frequency-weighting is mandated to be used for the protection of workers against noise-induced deafness and the only weighting mandated by the international standard, the frequency weightings “C” being optional fitments.
