Sper Scientific 850017 Integrating Sound Meter Calculates SPL and L EQ
Sper Scientific's Integrating Sound Datalogger measures sound pressure level (SPL) according to A or C weighting and integrates the weighted SPL over an established length of rime, such as an 8-hour workday,to calculate cumulative sound exposure (LEQ). Test parameters are simultaneously displayed on a large, bright, backlit display, featuring 0.1 dB resolution and a bar graph. Up to 64,000 data records can be stored in the meter, saved, graphed, and processed on a computer through the USB interface and included software. The bidirectional USB port and software also enable control of the meter via its on-screen image.
Features include SPL and LEQ sound level readings, fast and slow rime weighting, A and C frequency weightings, and over-limit and under-limit alarms. A single dynamic 30 to 130 dB range eliminates the need to manually select ranges and prevents data errors dudng range changes in auto-ranging models. The meter complies with IEC 61672-1 Class 2, ANSI Sl.4 Type 2 standards. 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, recorder output plug, 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
DIM: 10%" x 3Y2" x 1Y2" (273 x 89 x 38 mm). WEIGHT: 14.6 oz (414 g).
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.
