Accurate, professional measurements

This hand-held meter combines a capacitive microphone with a high‑precision temperature and humidity sensor to give reliable readings. It offers A and C frequency weighting plus fast and slow time weighting (1.25s fast), with an accuracy of ±1.5dB (94dB@1kHz) and a frequency response of 31.5Hz–8.5kHz. Measurement range covers 30–130dB, suitable for a variety of environments.

Clear display and data logging

The 2.0‑inch TFT screen shows four digits at 0.1dB resolution and supports curve recording so you can watch noise changes over time (curve updates every 0.5s). Dynamic scale updates and a dynamic range of 3.50dB keep readings responsive, while overload/high/low indications and up to 30 alarm records (with time and type) help you track events. Brightness is adjustable from 5%–100% in 5% steps and the unit supports dual style (day/night) viewing.

Power, language and what’s in the box

The meter uses a built‑in 1500mAh/3.7V rechargeable lithium battery and includes a charging cable and storage bag. Features include language switching (Chinese/English), a date clock and adjustable sleep/auto‑shutdown settings (1–60 minutes). Note that colours may vary slightly and small measurement deviations are possible due to manual testing.
