?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 ¡À1.4 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 the Sper?Acoustical Calibrator.
