BK8650噪音計(jì)/BK-8650
中文介紹
BK8650噪音計(jì)是一款適用于多種場(chǎng)景的便攜式專業(yè)設(shè)備，廣泛應(yīng)用于工業(yè)監(jiān)測(cè)、環(huán)境評(píng)估、建筑工地、城市管理等領(lǐng)域。該設(shè)備采用一體化緊湊設(shè)計(jì)，配備高靈敏度電容式麥克風(fēng)，能夠捕捉31.5Hz至8000Hz頻率范圍內(nèi)的聲波信號(hào)。其測(cè)量范圍為低檔35dB至90dB，高檔75dB至130dB，解析度達(dá)到0.1dB，精確度為±1.5dB（參考94dB@1KHz）。BK8650還具備多種測(cè)量模式，包括等效連續(xù)聲級(jí)、瞬時(shí)峰值聲級(jí)等，并支持A、C頻率加權(quán)以及慢速和快速時(shí)間加權(quán)。設(shè)備內(nèi)置數(shù)據(jù)存儲(chǔ)模塊，可記錄多組測(cè)量結(jié)果，方便后續(xù)分析。此外，BK8650配備高對(duì)比度LCD顯示屏，支持自動(dòng)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(jié)構(gòu)采用防塵防濺設(shè)計(jì)，結(jié)合抗干擾電路優(yōu)化，即使在復(fù)雜聲場(chǎng)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(shè)計(jì)，能滿足長(zhǎng)時(shí)間戶外作業(yè)需求，同時(shí)提供USB接口用于數(shù)據(jù)導(dǎo)出和設(shè)備充電。
English Introduction
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.
