Sound Level Meter Unit UT352 — handheld noise measuring instrument

The Sound Level Meter Unit UT352 is a handheld noise measuring instrument designed for quick on-site checks of environmental and workplace noise. This compact sound level meter records sound pressure levels in decibels (dB) and provides straightforward measurements for maintenance, acoustic diagnostics and compliance verification. The unit is intended for field measurements where portability, ease of use and reliable level readings are required.

Advantages

The Unit UT352 combines a compact form factor with clear dB readout and user-focused controls to enable fast measurement workflows. Its design supports rapid spot checks and short-term monitoring without complex setup. The device offers reliable response for general noise monitoring, HVAC inspections and machine noise assessment, helping technicians and inspectors to obtain repeatable level readings on site.

Suitable for

• Environmental noise surveys and spot checks
• Workplace noise assessment and occupational safety checks
• HVAC system noise troubleshooting and verification
• Machine and equipment noise screening during maintenance
• General sound level monitoring for facility management

Key specifications

• Measurement quantity: Sound pressure level (dB)
• Form factor: Handheld, portable instrument
• Display: Digital readout for dB levels
• Measurement range: Designed for environmental and workplace noise levels
• Application areas: Field measurements, maintenance, diagnostics and compliance checks

How to use

Switch on the Unit UT352 and allow the microphone to stabilize before taking measurements. Position the instrument at the location where sound levels should be assessed, keeping the microphone pointed towards the noise source while avoiding obstruction. Read the dB value from the digital display; for comparative checks, hold the device in a consistent orientation and distance from the source. Use short-term readings for quick diagnostics or repeated spot measurements to identify trends across locations.

Usage recommendations

For more consistent results, perform measurements away from reflective surfaces and maintain a steady microphone orientation. Calibrate or verify the instrument with a reference sound source according to local procedures before critical compliance checks. When assessing workplace noise for hearing-protection decisions, combine sound level readings with time-weighted exposure considerations and relevant standards.
