Sound Level Meter 30-130 dB

This digital sound level meter measures noise from 30 dB to 130 dB with a resolution of 0.1 dB. It offers A and C frequency weighting for different acoustic assessments. The device includes a digital LCD display and relay output interface. It is suited for professionals needing portable sound monitoring.

Capacity and headroom

The meter covers a measurement range of 31.5 Hz to 8 kHz frequency and 30 dB to 130 dB sound level. Accuracy is rated at +/- 1.5 dB across this span. Fast and slow response time settings capture transient or steady noise. It runs on four included 1.5V batteries for immediate use.

Upgrade path

This unit replaces basic analog meters that lack digital resolution or dual weighting. The jump is worth it when 0.1 dB resolution and data logging via relay output are required. It is not for users needing frequency analysis beyond 8 kHz or measurements below 30 dB. The one-year manufacturer warranty covers defects.

Questions about this item

Will the 30-130 dB range and 0.1 dB resolution work with my older analog recorder that only accepts line-level input?

The meter provides a relay output interface rather than a direct line-level audio output, so you would need an external adapter or interface module to connect it to your analog recorder.

How can I verify the meter is reading accurately after I install the batteries and power it on?

Check that the LCD shows a reading within the 30-130 dB range, confirm the A or C weighting indicator matches your selection, and ensure the fast/slow response setting changes the display update speed as expected.

Does the package include the four 1.5 V batteries and instructions, or do I need to buy them separately?

The box contains the sound level meter, four 1.5 V batteries, and the instruction manual, so no additional items are required for basic operation.
