Velleman DEM201 Digital Sound level Meter

The Velleman DEM201 digital sound level meter offers a reliable and straightforward solution for monitoring environmental noise levels with professional-grade accuracy. Compact and intuitive in design, this instrument is ideal for a wide range of applications, from assessing workplace noise compliance and setting up home recording studios to checking ambient sound in schools, offices, or public venues. Its portability makes it equally suitable for field measurements and routine checks by health and safety officers, acoustic consultants, or hobbyists.

Technically, the DEM201 measures sound pressure across a broad range of 30 to 130 dB, with selectable A and C frequency weightings to match different measurement standards. The A-weighting approximates human hearing sensitivity, while C-weighting is better suited for assessing peak or low-frequency noise. A clear digital display shows readings with a resolution of 0.1 dB, and the device includes both fast and slow response settings for capturing transient or steady-state noise levels. Additional features include a maximum hold function, a built-in calibration check, and a low-battery indicator. Powered by a standard 9V battery, this meter combines practicality with dependable performance for everyday noise monitoring tasks.
