SV 973 is a Class 2 sound level meter with a wide frequency range up to 20 kHz. The unique feature of the SV 973 is the microphone in MEMS technology with a lifetime warranty. The meter’s measurement range from 25 to 130 dB enables its use in industrial and environmental noise measurements.
For measurements of noise at work, the intelligent sound exposure meter function limits the frequency range to 10 kHz and shifts the dynamic measuring range of sound level meter to 141 dB Peak. The instrument is easily calibrated in the field using an acoustic calibrator as the calibration begins automatically when the microphone is inserted into the calibrator. The SV 973 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 data are stored on built-in 8 GB memory and can be easily downloaded to a PC using the Supervisor or SVANPC++ software.
