Uni-T UT352 Sound Level Meter

The Uni-T UT352 Sound Level Meter is a professional-grade digital instrument engineered for precise noise level monitoring across diverse environments. It provides reliable acoustic data for industrial, environmental, and occupational safety assessments, ensuring compliance with noise regulations. With its robust sensor technology and intuitive interface, this device is an essential tool for professionals who require consistent and accurate sound pressure level measurements.

Advantages

This sound level meter offers exceptional versatility by supporting both A-weighting, which mimics human ear sensitivity, and C-weighting, which is ideal for evaluating machinery and high-intensity noise sources. The device features selectable response times to capture either rapid noise fluctuations or stable averages effectively. Its integrated memory capacity allows for the storage of up to 63 data sets, while the inclusion of MAX/MIN functions and over-range indicators ensures that critical noise events are never missed during monitoring sessions.

Suitable for

• Industrial noise monitoring and workplace safety compliance
• Environmental noise assessment in residential or public areas
• Testing acoustic performance of machinery and equipment
• Educational and laboratory research applications

This device may not be suitable for high-precision laboratory calibration tasks that require specialized class 1 instrumentation. It is also not intended for underwater sound measurements or environments with extreme temperatures that exceed the specified operating conditions of the device.

Key specifications

• Measurement range: 30 to 130 dB
• Accuracy: ±1.5 dB
• Frequency range: 31.5 Hz to 8000 Hz
• Frequency weighting: A and C
• Sampling rate: Fast (8 times/s) and Slow (1 time/s)
• Display: Backlit LCD with analog bar graph
• Data storage: 63 sets
• Power supply: 4 x 1.5V batteries

How to use

To begin using the Uni-T UT352, insert the provided batteries into the compartment and power on the device. Select the appropriate frequency weighting (A or C) based on your specific measurement requirements and choose the desired response time (Fast or Slow). Hold the meter at arm's length or mount it on a tripod to minimize interference from the operator. Use the Data Hold function to freeze readings when necessary, and utilize the MAX/MIN mode to track peak noise levels during your assessment period.

What to consider before purchase

• Verify if your application requires A-weighting or C-weighting capabilities
• Check if the 63-set memory capacity is sufficient for your data logging needs
• Ensure the measurement range covers the noise levels expected in your environment
• Consider the need for external data logging if you require continuous long-term monitoring

Usage recommendations: Always use the included windscreen when measuring outdoors to prevent wind noise from affecting the accuracy of your readings. Ensure the device is calibrated periodically if used for official safety compliance reporting.
