Product information
UNI-T UT353 Sound Level Meter
The UNI-T UT353 is a compact, high-precision sound level meter designed for quick and convenient monitoring of ambient noise. Equipped with a sensitive 1/2-inch condenser microphone and an easy-to-read LCD display with backlighting, the UT353 is suitable for both everyday use and more demanding tasks, such as in offices, schools, machine noise monitoring, industrial environments or public events.
Accurate and fast sound measurements
The device measures sound levels from 30 dB to 130 dB with an accuracy of ±1.5 dB and a resolution of 0.1 dB, making it possible to evaluate both quiet and noisy environments. The UT353 offers two sampling modes: fast (125 ms) and slow (1,000 ms), so you can adapt the measurement to changing acoustic conditions.
Practical functions and convenient operation
The UT353 is equipped with functions for ease of use, such as result retention (Data Hold), maximum and minimum value recording (MAX/MIN), overload indicator (OL), automatic shutdown, and low battery indicator. The backlit LCD screen (32 × 26 mm) allows results to be read even in dimly lit rooms.
Compact and lightweight
With an ergonomic design and a weight of 116 g, the UT353 fits comfortably in the hand and is easy to carry. The device is powered by three AAA batteries (included). The package also includes a wind shield to improve the accuracy of outdoor measurements.
