SVAN 953
Sound Level Meter & Analyzer, Type 2
 |
OVERVIEW
The SVAN 953 is all digital, Type 2 sound level meter along with analyser. Instrument is intended to general acoustic measurements, environmental noise monitoring, occupational health and safety monitoring.
Three acoustic profiles allow parallel measurements with independently defined filters and RMS detector time constants. Each profile provides significant number of results (like Leq, LMax, LMin, LPeak, Spl, SEL etc.). Advanced time history logging for each profile provides complete information about measured signal in nonvolatile 16 MB internal memory or external USB Memory Stick and can be easy downloaded to any PC using USB interface and SvanPC+ software.
Using computational power of its digital signal processor the SVAN 953 instrument can, simultaneously to the meter mode, perform real time 1/1 octave analysis including statistical calculations and FFT analysis. Acoustic dosimeter function is available with the SV 25_2 dedicated microphone. Fast USB 1.1 interface (12 MHz) creates real time link for the PC “front-end” application of the SVAN 953 instrument. The measurement results can be also downloaded to any PC using the RS 232 or IrDA interfaces.
Instrument is powered from four AA standard or rechargeable batteries (separate charger is required). The powering of the instrument from the External DC power source or USB interface is also provided.
Robust case and light weight design accomplish the exceptional features of this new generation instrument.
