UNI-T UT352 Sound Level Meter

From the shop's description

UNI-T UT352 Sound Level Meter UNI-T UT352 Sound Level Meter is a reliable handheld sound level meter engineered to measure environmental noise levels with precision. It supports both A-weighting and C-weighting modes mimicking human hearing sensitivity for A or offering a flatter response for machine-dominated environments. This instrument allows users to visualize real-time noise data via an LCD display and simulated analog bar graph, along with audible feedback, making ambient sound analysis straightforward and intuitive. With ranges spanning 30 to 130 dB across multiple selectable segments (e.g. 30–80 dB, 50–100 dB, 60–110 dB, 80–130 dB), the UT352 adapts to diverse noise environments. Users can choose between fast (125 ms) and slow (1 s) response times to capture sudden spikes or average out fluctuations. Temperature-compensated accuracy of ±1.5 dB ensures consistent performance; the meter automatically flags readings that exceed or fall below its measurement bounds. Built for convenience and endurance, the UT352 stores up to 63 data sets internally for later analysis. It offers both AC and DC analog outputs for external recording or integration with other instruments. Power flexibility is another highlight: it runs on four AA batteries or via external DC (6 V adapter), while auto power-off, low-battery warning, and backlight further enhance usability in the field. CE and UKCA certifications underscore its compliance with European standards. Features MAX/MIN modes. Auto power off (cancelable). 63 sets data storage. AC/DC analog signal output.
