臺灣群特CENTER320數(shù)位式噪音計/CENTER-320
中文介紹
臺灣群特CENTER320數(shù)位式噪音計是一款專為噪音工程、品質(zhì)控制、健康防治以及各種環(huán)境噪音測量而設(shè)計的高精度儀器。它適用于工廠、學校、辦公室、交通道路、家庭、音響等多種場合的噪音測量。
該設(shè)備具備三種測量范圍：低檔（30dB～80dB）、中檔（50dB～100dB）和高檔（80dB～130dB），能夠滿足不同環(huán)境下的測量需求。其頻率響應范圍為31.5Hz～8kHz，能夠覆蓋大多數(shù)常見噪音頻率。此外，CENTER320還具備A和C兩種頻率加權(quán)特性，以及快速（FAST，125毫秒）和慢速（SLOW，1秒）兩種時間加權(quán)特性，用戶可以根據(jù)測量需求靈活選擇。
設(shè)備采用1/2英寸極化電容式麥克風，確保測量數(shù)據(jù)的準確性和穩(wěn)定性。其4位數(shù)字顯示，解析度達到0.1dB，更新速度為2次/秒，能夠?qū)崟r反映噪音水平。此外，設(shè)備還具備最大讀數(shù)鎖定（MAX HOLD）和最小讀數(shù)鎖定（MIN HOLD）功能，方便用戶記錄測量過程中的極值。
CENTER320的電源為單一9V電池，電池壽命長達約50小時（使用堿性電池），適合長時間的測量工作。設(shè)備的操作溫濕度范圍為0℃～40℃，10%RH～75%RH，能夠適應多種環(huán)境條件。其外形尺寸為275×64×30mm，重量僅約275克（含電池），便于攜帶和操作。
English Introduction
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.
