Key features

Compact handheld meter measuring 30–130 dB with A and C weighting options. It shows readings to 0.1 dB with a noise accuracy of ±1.5 dB.

Fast sampling is 125 ms for quick fluctuations and Slow is 1 second for steady averages. Frequency response covers 30 Hz to 8 kHz for typical environmental noise checks.

Power & models

Two model choices: ZL82A runs on 3×AAA batteries and ZL82B uses USB charging while delivering the same measurement performance. AAA batteries are not included with the battery model.

USB charging is convenient for top-ups on the go, while the battery option suits locations without USB power. Choose the model that fits your working environment.
