SV 973 is an extremely small Class 2 IEC 61672-1:2013 Sound
Level Meter (SLM) with the real time 1/1 & 1/3 octave analyser
option and Sound Exposure Meter (SEM) conforming to
international standards ISO 9612 and OSHA (IEC 61252;
ANSI S1.25).
The unique feature of SV 973 is the microphone in MEMS
technology with a lifetime warranty.
The user interface of this instrument makes measurement
configuration as easy as possible. This all makes SV 973 an ideal
choice for industrial hygiene noise measurements, audiometric
tests, short period environmental noise measurements, acoustics
consultancy surveys, technical engineers dealing with noise issues
and general acoustics noise measurements.
SV 973 provides broad band results with all required frequency
weighting filters plus real time 1/1 octave & 1/3 octave spectra in
the audio range.
The instrument enables huge time history logging capability
providing broad band results and spectra with adjustable double
(long and short) logging steps. Audio recording on user selectable
trigger conditions complete the logging functionality. Data are
stored on 8GB built-in micro SD chip and can be easily
downloaded to a PC (with the provided SvanPC++ software) over
the USB-C or optional RS 232 interfaces.
Direct printing feature enables quick on-site printing with the use
of optional portable printer.
The instrument can be easily calibrated in the field using an
acoustic calibrator.
Thanks to a robust pocket size housing and Low Energy Long
Range Bluetooth
®1
Smart wireless interface, this instrument is an
excellent tool for anyone who deals with acoustic measurements.
The instrument works with Svantek’s dedicated health and safety software packages – Supervisor for
data downloading, visualization, basic post-processing and exporting to commonly used office software
applications and also with the full analysis package SvanPC++.
