Digital Sound Level Meter

Digital Sound Level Meter

NOISE MEASUREMENT MADE EASY The AutoTest® Digital Sound Level Meter is a must have OH&S tool for any garage.

  1. Compliant with IEC 651 Type 2 and ANSI S1.4 Type 2
  2. Accurate and easy to use
  3. Measurement range of 30 – 130 dbA
  4. MAX mode for maximum noise capture
  5. Fast and slow modes
  6. AC output for frequency and analyser level recorder, FFT analyser, graphic recorder etc.
  7. Calibrate with the AutoTest Acoustic Calibrator

AutoTest® Digital Sound Level Meter is used to measure and monitor noise levels to ensure that volume levels are within tolerances or an expected range in any industrial or domestic application.

This sound and vibration tool is commonly used to test automotive exhausts volume in road worthy checks carried out by an Approved Inspection Station (AIS).

A sound level meter can also be used to monitor sound levels within work places, such as factories and plants and ensure that employees are guided to wear hearing protection when excessive noise levels are present. It is also commonly used on construction sites when commercial machinery such as excavators and bulldozers are used.

Other uses include road noise studies for setting up sound breaks along freeways and also for ensuring concerts and public events maintain an acceptable volume within local regulations. Sensitivity can be adjusted for different ambient conditions and environments.

Features

  1. The unit complies with IEC651 TYPE 2 & Ansi S1.4 TYPE 2 for sound level meters
  2. Instantaneous level measurement
  3. Measurement range: 30 - 130 decibel
  4. With two equivalent weighted sound pressure levels, A and C
  5. Fast and slow modes
  6. AC output for frequency and analyser level recorder, FFT analyser, graphic recorder etc

Operation Directions

  1. Turn on power.
  2. Select desired response and weighting, also select desired range.
  3. If weighting for general noise sound level, please select dBA.
  4. If the sound source consists of short bursts, set response to FAST.
  5. To measure average sound level, use the SLOW setting.
  6. When MAX mode is chosen, the instrument will capture and hold the maximum noise level.
