Digital Decibel Meters and Noise Measurement Instruments for Workplace and Environmental Testing

Explore our range of sound level meters built for accurate noise measurement in factories, workshops, construction sites, schools, and public spaces. At nanozone.lk, we supply digital decibel meters that help safety officers, engineers, and facility managers measure noise exposure, check compliance, and investigate sound problems with confidence.

Our collection includes handheld noise meters and precision integrating models that measure sound pressure level (SPL) in dB with A, C, and Z frequency weighting and Fast, Slow, and Impulse time weighting. Choose a simple noise level meter for quick spot checks. For standards-based assessments, choose a data-logging model that meets IEC 61672-1 for workplace, environmental, and product noise evaluation.

How to Choose the Right Sound Level Meter

Accuracy Class
Class 1 meters offer tighter tolerances and a wider frequency range for formal surveys and reports. Class 2 meters suit general-purpose noise checks and routine monitoring.
Measurement Functions
Look for Leq (equivalent continuous level), SEL, and peak measurement for exposure assessment, and A/C/Z weighting for different noise types.
Data Logging and Connectivity
Models with internal memory, SD card storage, or USB and RS-232 outputs let you record long-term readings and analyse them on a PC.
Calibration
Regular field checks with an acoustic calibrator (typically 94 dB at 1 kHz) keep readings reliable and traceable.
