Compact 4in1 environmental monitor that combines a sound meter, thermometer, humidity meter, and clock into a single device for simple, continuous monitoring of indoor conditions. Key benefits Consolidates four measurements in one unit, reducing the need for multiple instruments and making it easier to track environment and noise levels. Semiconductor air sensor delivers sensitivity and reliable readings for temperature, humidity, and decibel values. Large 11 inch LED color display shows time, temperature, humidity, and decibels at a glance, with adjustable brightness for comfortable viewing in any light. Sixstep decibel indicator uses three colors and three symbols to show noise intensity at a glance, helping you identify quiet, moderate, and loud environments quickly. Useful for monitoring and troubleshooting HVAC performance, adjusting room comfort, and checking noise levels without complex setup. Features and specifications Functions: sound meter, thermometer, humidity meter, clock. Sensor type: semiconductor air sensor for accurate and responsive measurement of temperature, humidity, and decibel levels. Display: 11 inch large LED color screen with time, temperature, humidity, and decibel readouts; brightness adjustable to suit different lighting conditions. Decibel indicator: six gears with color coding in green, yellow, and red plus three indicator symbols for intuitive interpretation. Design focus: clear, ataglance information to support quick decisions about the ambient environment and sound level. Practical applications Home: Monitor living areas to locate noisy appliances, check relative humidity for comfort, and keep an eye on room temperature and time. Office or classroom: Track ambient noise and environmental conditions to maintain a productive work or learning setting. Small project spaces and workshops: Verify noise levels during tool operation and monitor temperature and humidity where equipment or materials are sensitive to environmental changes. Why this product stands out Integrates four essential environment and sound measurements into a single, easytoread instrument. Semiconductor sensing provides higher sensitivity and responsiveness compared with basic sensors. Visual decibel levels with color and symbol cues make it simple to interpret noise without reading detailed numbers. Large, adjustable LED display puts all key data in one view for quick assessment. Suitable environments Intended for indoor use in homes, offices, classrooms, studios, workshops, and similar spaces where monitoring temperature, humidity, time, and sound level is helpful. What is included Device with builtin semiconductor sensor and 11 inch LED display supporting time, temperature, humidity, and decibel readouts and a sixgear decibel indicator with color and symbol guidance.
