Product Features
The SvanTek SV 973 combines Class 2 sound level meter and sound exposure meter in one device. The metre is built in line with IEC 61672, and it has a frequency range of up to 10 kHz (in the sound level metre mode). The SV973's microphone is made of MEMS technology and comes with a lifetime warranty.
The measurement range of the metre allows it to be used in both industrial and environmental noise measurements. The specific sound exposure metre function raises the dynamic measuring range of the sound level metre to 141 dB Peak for noise measurements at work. d sound exposure meter function shifts the dynamic measuring range of sound level meter up to 141 dB Peak. The instrument is easily calibrated in field using an acoustic calibrator as the calibration begins automatically when the microphone is inserted into the calibrator.
The SV973 can measure broad-band results with all the necessary weighting filters as well as 1/1 octave or 1/3 octave band filters. Audio events recording function works together with sound level meter mode. The reverberation time (RT 60) function is also available as and option. The data are stored on built-in 8GB memory and can be easily downloaded to a PC using the Supervisor or SVANPC++ software.
A Class 2 Sound Level Meter is a noise measurement instrument that complies with IEC 61672 regulations. A microphone, a preamplifier, a signal processor, and a display that displays noise results are all included. The class 2 specification is fairly similar to the class 1 specification, but it differs in terms of acceptance limits and operational temperature range. Acceptance limitations in class 2 are greater than or equivalent to those in class 1.
