English Introduction
The CENTER 321 sound level meter is a professional and precise acoustic measurement instrument, designed to meet a variety of noise monitoring needs. It uses advanced acoustic sensor technology to quickly and accurately capture noise signals in the environment and convert them into intuitive numerical displays. With a wide measurement range, it can cover various noise scenarios from extremely low to relatively high decibel levels. Whether it is the roar of machinery in industrial workshops, the noisy construction on building sites, the hustle and bustle of city streets, or the subtle sounds in indoor environments, it can measure accurately and provide reliable data support for users.
This device is easy to operate, with a simple and intuitive user interface that even first-time users can quickly get started with. It has a number of practical functions, such as data storage, which can save measurement results in the device s memory for users to review historical data and conduct comparative analysis at any time. The data output function supports connection with computers and other devices, facilitating further data processing and report generation. This meets the diverse needs of users in noise monitoring, evaluation, and research. In addition, its robust and durable housing design can adapt to various complex working environments, ensuring stable performance of the device over long-term use. It is an indispensable noise measurement tool in fields such as environmental monitoring, industrial production, construction, and scientific research and teaching.
