台湾群特CENTER320数位式噪音计是一款专为噪音工程、品质控制、健康防治以及各种环境噪音测量而设计的高精度仪器。它适用于工厂、学校、办公室、交通道路、家庭、音响等多种场合的噪音测量。

该设备具备三种测量范围：低档（30dB～80dB）、中档（50dB～100dB）和高档（80dB～130dB），能够满足不同环境下的测量需求。其频率响应范围为31.5Hz～8kHz，能够覆盖大多数常见噪音频率。此外，CENTER320还具备A和C两种频率加权特性，以及快速（FAST，125毫秒）和慢速（SLOW，1秒）两种时间加权特性，用户可以根据测量需求灵活选择。

设备采用1/2英寸极化电容式麦克风，确保测量数据的准确性和稳定性。其4位数字显示，解析度达到0.1dB，更新速度为2次/秒，能够实时反映噪音水平。此外，设备还具备最大读数锁定（MAX HOLD）和最小读数锁定（MIN HOLD）功能，方便用户记录测量过程中的极值。

CENTER320的电源为单一9V电池，电池寿命长达约50小时（使用碱性电池），适合长时间的测量工作。设备的操作温湿度范围为0℃～40℃，10%RH～75%RH，能够适应多种环境条件。其外形尺寸为275×64×30mm，重量仅约275克（含电池），便于携带和操作。

The Taiwan QunTe CENTER320 Digital Noise Meter is a high-precision instrument designed for noise engineering, quality control, health prevention, and various environmental noise measurements. It is suitable for measuring noise in a wide range of settings, including factories, schools, offices, traffic roads, homes, and audio environments.

This device offers three measurement ranges: low range (30dB to 80dB), medium range (50dB to 100dB), and high range (80dB to 130dB), catering to different environmental needs. Its frequency response ranges from 31.5Hz to 8kHz, covering most common noise frequencies. Additionally, the CENTER320 features both A and C frequency weighting characteristics, as well as fast (FAST, 125 milliseconds) and slow (SLOW, 1 second) time weighting characteristics, allowing users to choose according to their measurement requirements.

Equipped with a 1/2-inch polarized condenser microphone, the CENTER320 ensures accurate and stable measurement data. The device has a 4-digit display with a resolution of 0.1dB and an update speed of 2 times per second, providing real-time noise level readings. It also features maximum (MAX HOLD) and minimum (MIN HOLD) reading lock functions, which facilitate the recording of extreme values during the measurement process.

Powered by a single 9V battery, the CENTER320 has a battery life of approximately 50 hours (using alkaline batteries), making it suitable for long-duration measurement tasks. The device can operate within a temperature and humidity range of 0℃ to 40℃ and 10%RH to 75%RH, respectively, allowing it to function in various environmental conditions. With dimensions of 275×64×30mm and a weight of only about 275 grams (including the battery), the CENTER320 is portable and easy to use.
