Product description

The description on the packaging box identifies the device as an “air quality monitor.” Is this an error?

Based on our initial assessment—that noise propagates through the air—we had classified the decibel meter/noise detector as an “air quality monitor.” We have since revised the packaging design to correct this. Thank you for your valuable advice.

In which scenarios is this recommended for use?

Industrial-grade noise detectors differ in accuracy from home-use models; therefore, we recommend this specific noise detector for use in home environments, like office, bedroom, classroom, music room or etc.

What is the difference between a plug-in noise meter and a handheld noise meter?

Plug-in decibel meters are better suited for long-term indoor monitoring and surveillance, whereas handheld noise meters are more suitable for immediate, on-the-spot measurements.

Who is this innovative noise detector recommended for?： This innovative plug-in noise detector supports continuous monitoring and provides a real-time, intuitive display of noise levels. It is ideal for individuals who wish to monitor their daily living environment, for use in venues with specific noise regulations, or for tenants seeking to assess noise conditions and avoid potential disturbance issues
3-in-1 Plug In Decibel Meter: Simply insert the plug into any outlet to instantly start tracking noise (30–130 dBA), temperature, and humidity—no batteries or setup required. This compact noise detector works as a real‑time sound level meter, displaying everything on a crisp 1.83” color screen visible from 15 ft away
Intuitive Controls with Built‑in Decibel Meter: Adjust screen brightness or flip the display upside down with a single button. Use the dedicated decibel meter functions to view MAX/MIN readings over 24 hours, switch between °F/°C, or freeze current values. Whether you need a reliable noise monitor for an RV or a home office, the controls are designed for effortless operation
High‑Speed Accuracy with a Noise Level Meter: Stay on top of changing environments thanks to rapid data refresh rates—temperature and humidity update every 2 seconds. As a precision sound meter, you can choose “FAST” (0.125s) response for sudden sounds or “SLOW” (1s) for ambient trends, making this noise level meter ideal for home, workshops, or travel
Instant Visual Alerts with an SPL Meter: The color‑coded UI bar gives you immediate feedback on noise severity—green (<60 dBA), yellow (60–75 dBA), orange (75–85 dBA), or red (≥85 dBA). Acting as both an SPL meter and an audio level meter, it lets you glance from across the room to see if sound levels are safe, comfortable, or require attention
Ultra‑Portable Decibel Monitor & Ambient Noise Sensor: Weighing only 2.1 oz (60g) and supporting worldwide voltage (110–240V), this sleek device is built for life on the go. Use it as a reliable decibel monitor in a camper van or as a versatile ambient noise sensor for a home office—all while enjoying plug‑and‑go convenience and a modern, travel‑ready design
