Impulse Sound Level Meter with Three Time Weightings

The LANDTEK SL-5868I is an impulse sound level meter that measures exponential time-weighted sound levels and impulse noise. It conforms to GB/T 3785-2010 level 2, IEC 61672:2013 Class 2, and JJG 188-2017 standards. The instrument offers selectable Fast, Slow, and Impulse time weightings alongside A, C, and Linear frequency weightings. A 12.7 mm condenser microphone captures sound across a 25 dB to 130 dB range.

Target Users and Limitations

This meter suits technicians and electricians who need Class 2 accuracy for environmental or industrial noise assessments requiring impulse detection. The three selectable time weightings support both standard and transient noise analysis. It is not for users who require Class 1 precision or data logging capabilities not described in the specifications. Buyers needing automated range selection should also consider other instruments.

Manual Three-Gear Range Control

Range selection is managed manually across three linear gears, each providing a linear span greater than 60 dB. The specific measurement windows are 30 dB to 90 dB, 50 dB to 110 dB, and 70 dB to 130 dB, with corresponding dynamic scale displays of 10 to 100, 30 to 120, and 50 to 140. Correct gear selection is essential to match the expected sound pressure level and maintain reading accuracy.

Questions about this item

What does the 130 dB upper limit mean when I am using the meter on site?

The instrument can measure sound pressure levels up to 130 dB on the A-weighting scale, so very loud industrial or traffic noise stays within range without overloading.

How do the Fast, Slow and Impulse time weightings change the reading in practice?

Fast reacts quickly to brief events, Slow smooths fluctuating sources like machinery, and Impulse captures short high-level peaks such as impacts or gunshots.

What physical space does the 12.7 mm microphone need for mounting?

The half-inch condenser microphone fits standard 12.7 mm mounts and tripod threads used by most sound-level-meter accessories.
