(April 30, 2025) In our latest Giveaway, you can win a TOPTES TS-501B Handheld Sound Level Meter! The TS-501B is a compact, battery-powered device designed for both DIY enthusiasts and professionals who need quick, reliable noise measurements. Equipped with a precision condenser microphone and selectable A- and C-weighting, it captures sound pressure levels from 30 to 130 dB within ±1.5 dB accuracy over a 30 Hz–8 kHz frequency range. Readings are displayed on a generous 2.25-inch backlit LCD, with Max/Min and data-hold functions to freeze peak or valley values, and fast (125 ms) and slow (1 s) time-weighting modes to suit varying noise environments. Its ergonomic, anti-slip housing, auto power-off feature, low-battery indicator, and included carry pouch make the TS-501B a practical tool for home-theater calibration, workshop monitoring, or environmental noise assessments.
