30dB to 130dB Range: Covers standard environmental, residential, and industrial noise spectrums.
0.1dB Resolution: Delivers ultra-fine measurement details with $pm1.5text{dB}$ accuracy.
Fast/Slow Dual Sampling Rates: Toggle between 125ms (Fast) for real-time impact noise and 1s (Slow) for steady-state background averages.
Windscreen Cap Included: Comes with a custom foam windscreen to block ambient air interference during outdoor audits.
Excessive noise is more than a distraction—it is a hazard to health, productivity, and local regulatory compliance. The UNI-T UT353 Mini Digital Sound Level Meter offers a reliable, low-profile, and incredibly easy-to-use diagnostic solution to measure noise levels on the spot.
Weighing just 116 grams, this pocket-friendly decibel meter easily slips into a toolbox or glove compartment. It features a robust, ergonomic body with a non-slip grip, making it a favorite for safety officers, acoustic engineers, HVAC contractors, and automotive mechanics checking exhaust or cabin insulation performance.
The UT353 is engineered with a high-performance 1/2-inch condenser microphone that processes incoming sound waves with elite stability. To adapt to different noise sources, the meter includes two specialized sampling rates:
Fast Mode (125ms): Captures sudden spikes, impact noises, and transient fluctuations (like a car horn or machinery startup).
Slow Mode (1000ms): Smooths out fluctuating sound waves to calculate consistent, cumulative background noise levels (like office HVAC hums or street traffic).
One-Touch Min/Max Capture: Easily scan an environment to record and lock the absolute quietest and loudest decibel levels over a testing session.
Dual-State Overload Alerts: Displays a clear "UN" indicator if noise falls below 30dB, and a flashing "OL" warning if levels exceed the 130dB maximum safety threshold.
Auto-Illuminated Backlit Screen: Built with an intelligent light-sensing backlit display that automatically turns on in low-light environments, keeping readings clear in dark industrial spaces or late-night audits.
Anti-Interference Windscreen: Includes a durable, slip-on foam windscreen designed to filter out high-velocity air currents, ensuring accurate readings when testing outdoors or near forced air vents.
