Svantek SV 973A Class 2 Sound Level Meter

Add to Wish List Email to a Friend

The SV 973A from Svantek is a Class 2 sound level meter with a wide frequency range up to 10 kHz. The unique feature of the SV 973A is the microphone in MEMS technology with a lifetime warranty. The meter’s measurement range from 25 to 128 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.
