About This Product

The meter is used to measure sound levels in the environment and the noise of machinery. A weighting follows the response of the human ear and is the usual choice for environmental measurements, while C weighting is close to a flat response and suits checking machinery noise. A built-in adjustment screw and an internal 1 KHz sine wave generator are provided for calibration. The Digital Sound Level Meter can be ordered by schools and distributors in Suriname, Kyrgyzstan, Uruguay, Cabo Verde and Bhutan.

Frequently Asked Questions

When should A or C weighting be used?

A weighting simulates the response of the human ear and is typically selected for environmental sound level measurements. C weighting is near a flat response and suits checking machinery noise and the sound pressure level of tested equipment.

What do the Fast and Slow settings do?

Fast uses a 200 ms time weighting that simulates the response time of the human ear. Slow uses 500 ms and makes it easier to get average values of a varying sound level.
