The Larson Davis System 824 combines advanced sound level meter and real-time analyzer capabilities into a rugged, user-friendly, ergonomic package. The base unit is an Integrating Sound Level Meter (ISM) that meets Type 1 Standards and offers simultaneous measurement of sound pressure levels using fast, slow, and impulse detectors, for A, C, and flat frequency weightings. This feature, termed ANY LEVEL™ measures 48 sound pressure parameters at once with a linear, 105 dB range. With firmware enhancements, the base unit expands as needed to accommodate multiple data processing requirements, including:
Sound Spectrum Analyzer (SSA) with ANY LEVEL™ simultaneous sound pressure level measurement, real-time 1/3 octave frequency analysis, spectral Lns and multiple time histories. This is your do everything at once instrument.
Real-time Frequency Analyzer (RTA) provides rapid storage of 1/3 octave spectra at rates to 400/second, advanced trigger functions and automated determination of reverberation time.
Fast Fourier Transform Analyzer (FFT) with 400-line resolution from 1 Hz to 20 kHz for specific frequency investigations. Includes snapshot data storage, THD calculations, user definable linear units, and more.
Logging Sound Level Meter (LOG) provides advanced time and data logging features, including automatic logging of data associated user-defined noise events.
As with all Larson Davis products, this equipment is complemented with toll free applications assistance, 24-hour customer service, and is backed by a no-risk policy that guarantees satisfaction or your money refunded.
