Sper Scientific 850013C Advanced Datalogging Sound Meter, NIST Certificate of Calibration
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. 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 850016. Comes in a foam lined, protective carrying case, complete with a windscreen, USB computer connection cable, software, instructions, calibration tool, and 4 AA batteries which provide about 30 hours of use. The optional microphone extension cable enables remote measurements. N.I.S.T. traceable certificate of calibration available.

Weight: 14.6 oz (414 g)
ANSI S1.4 Type 2
Specifications for Sound Level Meters
The American standard for sound level meter performance. Very similar to IEC 60651. Grades in order of accuracy: Type 1, Type 2
IEC 61672-1 Class 2.
Electroacoustics - Sound level meters
This is the most recent sound level meter standard and the one that modern measurement regulations will require. Grades in order of accuracy: Class 1, Class 2
Comes with a NIST certificate of calibration. The NIST certificate specifies that the standards against which the product has been certified or calibrated were themselves calibrated by the National Institute of Standards and Technology (N.I.S.T.), or with N.I.S.T. calibrated equipment under conditions specified by N.I.S.T.
