Digital Handheld Sound Level Meter 30-130dB — Color Screen Noise Meter with A/C Weighting, Accurate Readings

Portable digital sound level meter for noise engineering, quality control, filming locations, construction sites, automotive noise checks, and home/school health protection. The unit features a color screen display and delivers stable, reliable and precise decibel measurements across a 30–130dB range. To enable communication, power the instrument on and press-and-hold the button; an on-screen indicator will confirm the communication function is active. Includes A-weighting to simulate the human ear’s response to low-intensity sounds (below 55 dB) and C-weighting for high-intensity mechanical noise; the C-weighting mode is suitable for fluctuating or unstable transportation noise. Use the meter to measure steady-state noise where the displayed reading represents the effective (RMS) value.You may also like A12 5M Tiny IOT Waterproof Ultrasonic Water Level Sensor — Easy to Use Distance Measurement.
