Sper Scientific 850013 Advanced Datalogging Sound Meter
A single dynamic 30 ~ 130 db range
A single dynamic 30 ~ 130 db range eliminates the need to manually select ranges and prevents data errors during range changes in auto-ranging models. All test parameters are simultaneously displayed on a large bright back-lit display featuring 0.1 dB resolution and a bar graph. Automatically log up to 31,000 records for later download, or manually save and recall 99 data points, with date and time stamp, directly on the meter’s LCD. The bi-directional USB port and software also enable control of the meter via its on screen image.
