BK8650噪音計是一款適用于多種場景的便攜式專業(yè)設備，廣泛應用于工業(yè)監(jiān)測、環(huán)境評估、建筑工地、城市管理等領域。該設備采用一體化緊湊設計，配備高靈敏度電容式麥克風，能夠捕捉31.5Hz至8000Hz頻率范圍內(nèi)的聲波信號。其測量范圍為低檔35dB至90dB，高檔75dB至130dB，解析度達到0.1dB，精確度為±1.5dB（參考94dB@1KHz）。BK8650還具備多種測量模式，包括等效連續(xù)聲級、瞬時峰值聲級等，并支持A、C頻率加權以及慢速和快速時間加權。設備內(nèi)置數(shù)據(jù)存儲模塊，可記錄多組測量結果，方便后續(xù)分析。此外，BK8650配備高對比度LCD顯示屏，支持自動背光調(diào)節(jié)，確保在不同光照條件下都能清晰讀數(shù)。其結構采用防塵防濺設計，結合抗干擾電路優(yōu)化，即使在復雜聲場中也能保持穩(wěn)定工作。內(nèi)置可充電鋰電池，配合低功耗設計，能滿足長時間戶外作業(yè)需求，同時提供USB接口用于數(shù)據(jù)導出和設備充電。

The BK8650 Noise Meter is a portable professional device suitable for a variety of scenarios, widely used in industrial monitoring, environmental assessment, construction sites, and urban management. This device features an integrated compact design and is equipped with a high-sensitivity condenser microphone, capable of capturing sound wave signals within a frequency range of 31.5Hz to 8000Hz. Its measurement range is from 35dB to 90dB on the low range and from 75dB to 130dB on the high range, with a resolution of 0.1dB and an accuracy of ±1.5dB (referenced to 94dB@1KHz). The BK8650 also supports various measurement modes, including equivalent continuous sound level and instantaneous peak sound level, and offers A and C frequency weighting as well as slow and fast time weighting. The device is equipped with a built-in data storage module that can record multiple sets of measurement results for subsequent analysis. Additionally, the BK8650 features a high-contrast LCD screen with automatic backlight adjustment to ensure clear readings under different lighting conditions. Its structure is designed to be dustproof and splash-proof, combined with optimized anti-interference circuits, ensuring stable operation even in complex sound fields. The device is powered by a rechargeable lithium battery and features low power consumption design, which can meet the needs of long-term outdoor operations. It also provides a USB interface for data export and device charging.
