SNDWAY SW-525A 130dB Wall Mounted Sound Level Meter

SKU CH-XN9K-5AVX4

Wall-mounted meter measures noise from 30 to 130 dB with ±1.5 dB accuracy at 94 dB and fast response

  • Measures noise from 30 to 130 dB
  • ±1.5 dB accuracy at 94 dB reference tone
  • Covers 31.5 Hz to 8.5 kHz frequency range
  • A-weighting matches human hearing response
  • Fast response captures sudden sound changes

Accurate Noise Monitoring

The SNDWAY SW-525A measures sound pressure from 30 to 130 dB with an accuracy of ±1.5 dB at the 94 dB reference level. It uses A-weighting and a fast response time to track ambient noise in factories, offices, homes and traffic environments. The meter covers a frequency range of 31.5 Hz to 8.5 kHz for broad-band analysis.

Stable Wall-Mounted Operation

Designed for fixed installation, the unit draws minimal power while continuously sampling sound levels. Its fast response setting captures sudden level changes without delay. The A-weighting filter matches human hearing sensitivity for consistent environmental readings across the stated frequency band.

USB Data Transfer on 525B Variant

Connecting the 525B model to a computer via USB enables record downloads, sample collection and chart printing. This functionality is specific to the 525B version and is not available on the base unit. The accessory extends the meter from a simple display to a logging tool for detailed acoustic reports.

Questions about this item

How is the SNDWAY SW-525A wall mounted and what step do people often miss?

Secure the meter to a vertical surface using the mounting holes on the rear casing. The step often missed is allowing the microphone grille to face the noise source without obstruction from walls or objects.

What maintenance or replacement will the SW-525A need over time?

The electret condenser microphone capsule can drift with age and humidity. Plan to recalibrate against a 94 dB @ 1 kHz reference source periodically and replace the capsule if readings exceed the ±1.5 dB tolerance.

What limit appears first during continuous high-level monitoring?

The upper measurement ceiling of 130 dB is reached before the 31.5 Hz–8.5 kHz frequency response or the fast time weighting become limiting factors.
