Noise Measurement with Maximum Versatility

The Sper Scientific Advanced Datalogging Sound Meter (Model 850013) uses a single range of 30 ~ 130 dB.  This dynamic range eliminates the need to manually select and change ranges, alleviating the problem of lost data associated with range changes in auto-ranging models.

All test parameters are simultaneously displayed on a large, bright backlit 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 enable control of the meter via its on-screen image, and the optional microphone extension enables up-close measurements of hard-to-reach areas.

Accurate within ±1.4 dB and meets or exceeds all other specs for an ANSI S1.4 and IEC 61672-1 Type 2 meter. Also features A/C and fast/slow weighting scales, min-max, over/under alarms, AC or DC recorder output and auto power off. Calibrate in compliance with OSHA using Acoustical Calibrator.
