PCE-354 LEQ Sound Level Meter

Key Features:

Wide measurement range: 30 dB to 130 dB — ideal for ambient noise, workplace noise and environmental sound monitoring.

Equivalent continuous noise level (Leq) measurement: Calculates the time-averaged sound level over a specified period, enabling accurate exposure assessments.

Peak and MAX-hold function: Captures and holds peak noise levels (Lpeak), facilitating quick identification of limit-exceedance events.

Frequency weighting and time weighting: Supports A- and C-weighting, and response times “Fast” (125 ms) and “Slow” (1 s) to match human hearing and regulatory standards.

Broad frequency range: 20 Hz to 12 500 Hz — enables measurement of low-frequency and high-frequency noise sources.

Data storage: Internal memory for 99 measured values (manual storage) for later documentation.

Backlit LCD display: Ensures readability in low-light conditions and on-site field environments.

Automatic power‐off: After ~10 minutes of inactivity to conserve battery life — convenient for field use.

Portable and ergonomic: Handheld lightweight design, suitable for quick checks, field surveys and occupational noise monitoring.

Class 2 accuracy: Meets general industrial and environmental measurement requirements (±1.5 dB typical accuracy) for cost-effective sound level monitoring.
