SV971 Sound Level Meter

SV971 Sound Level Meter

Product Introduction:
SVAN 971 is a very small Class 1 sound level instrument with options for 1/1 and 1/3 octave band analysis
The technology of this instrument has brought the state of * to the scale of SLM
The new user interface of the instrument makes configuration and measurement easier than ever before
For those without time measurement settings, SVAN 971 provides an extremely simple operating mode, start/stop
SVAN 971 provides broadband results with all necessary weighted filters plus 1/1 octave and 1/3 octave bandpass filters
It also provides an incredible historical record of time
• While triggering the complete recording function, it can also
The instrument can be easily calibrated for acoustic calibration used in this field
Inserting the microphone calibrator will automatically initiate the calibration process and automatically calibrate the history.
The data is stored on a μ SD card and can be easily downloaded to a PC using SvanPC++software provided via USB or RS-232 interface
The instrument can be easily calibrated for acoustic calibration used in this field
Inserting the microphone calibrator will automatically initiate the calibration process and automatically record the calibration history
New PC software will assist supervisors
The measurement frequency and creation of SVAN 971 owner organization data are faster and more effective than ever before in measuring reports
