Digital Sound Level Meter 30130 dB Range, LED Display, Desktop Noise Meter, Time Temperature Humidity Indicator Description

This desktop decibel meter combines sound level measurement with environmental monitoring and time functions in a single unit. It is designed for ease of use on any desk and for continuous monitoring in various settings. Key benefits User friendly interface: adjust brightness with the left button, decrease brightness with the right button, and long press M to set the time. Temperature readings can be shown in Celsius or Fahrenheit. Allinone measurement: measures sound levels with Aweighted SPL, plus temperature and humidity, and provides clock and timer functions. Clear visibility: large definition LCD makes it easy to read readings at a glance from a desktop. Long battery life: builtin 2000 mAh lithium battery supports 3 to 5 days of continuous use and up to a week on standby. Consistent, reliable data: designed to monitor ambient conditions and noise with a compact, desktopfriendly form factor. What it measures and how accurately Sound level: 30 to 130 dB range with accuracy of 1.5 dB. Frequency response: 35 to 8.5K Hz. Humidity: 20 to 85 percent RH. Temperature: 10 C to 60 C or 14 F to 140 F. Notes: due to varying environmental conditions, a reading deviation of 0 to 15 percent is normal. Functionality and design Multifunction display: the meter serves as a sound level meter, thermometer, hygrometer, clock, and timer. Aweighted SPL: the measurement mimics the human ear's sensitivity to lowintensity sounds, making it suitable for ambient noise monitoring. Desktop usability: designed for stable placement on desks, benches, or workstations. Battery and endurance Builtin 2000 mAh lithium battery. Battery life: approximately 3 to 5 days of continuous use, up to 7 days on standby. Ideal for extended monitoring in studios, classrooms, and industrial environments. Use scenarios Studio or recording environment: monitor ambient noise levels during sessions to protect hearing and ensure compliance with noise standards, while also tracking room conditions. Classroom or library: keep noise within acceptable limits to maintain a conducive learning environment, and monitor temperature and humidity to ensure comfort and equipment performance. Industrial or workshop settings: provide ongoing ambient noise and environmental condition monitoring to support safety and workflow efficiency.
