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.
