在功能配置方面，SL-5866提供MAX/MIN瞬時(shí)值記錄、數(shù)據(jù)保持以及手動(dòng)存儲(chǔ)功能，支持累積1000組測(cè)量數(shù)據(jù)存儲(chǔ)。內(nèi)置可充電鋰電池可連續(xù)工作30小時(shí)，配合低功耗待機(jī)模式，滿足長(zhǎng)時(shí)間監(jiān)測(cè)需求。防護(hù)等級(jí)達(dá)到IP54，可在-10℃至50℃環(huán)境下穩(wěn)定運(yùn)行，防塵防濺設(shè)計(jì)提升設(shè)備耐用性。
該產(chǎn)品適用于工廠車間噪聲檢測(cè)、設(shè)備運(yùn)行狀態(tài)監(jiān)測(cè)、環(huán)境評(píng)估調(diào)查、公共空間聲學(xué)管理等多個(gè)專業(yè)領(lǐng)域，為工程技術(shù)人員、環(huán)境監(jiān)測(cè)人員及管理人員提供可靠的數(shù)據(jù)支持。通過優(yōu)化傳感器布局與電路設(shè)計(jì)，設(shè)備在復(fù)雜聲場(chǎng)環(huán)境中仍能保持測(cè)量一致性，是現(xiàn)場(chǎng)噪聲管理的實(shí)用工具。
【English Version】
The SL-5866 Sound Level Meter is a professional environmental noise monitoring instrument designed for acoustic measurement applications across industrial inspection, environmental protection, construction sites, and community management scenarios. Equipped with digital signal processing technology and high-sensitivity sensors, this device accurately captures audio signals within 20Hz to 12.5kHz frequency range, delivering precise measurements from 30dB to 130dB. Its compact design and intuitive interface ensure efficient on-site operation.
Featuring a 2.4-inch LCD screen with real-time sound level curve display, the device enables instant data visualization for quick interpretation. Three selectable time weighting modes (Fast/Slow/Impulse) adapt to varying environmental conditions, while built-in A/C frequency weighting effectively simulates human auditory characteristics for perceptually relevant measurements. The specially designed windscreen minimizes airflow interference during outdoor operations.
Functional configurations include MAX/MIN value recording, data hold function, and manual storage capacity for 1000 measurement datasets. Powered by a rechargeable lithium battery with 30-hour continuous operation and low-power standby mode, it supports extended monitoring tasks. With IP54 protection rating and operational range from -10℃ to 50℃, the dustproof and splash-resistant construction enhances durability in challenging environments.
This instrument serves multiple professional fields including industrial facility noise assessment, equipment operation monitoring, environmental evaluation studies, and public space acoustic management. Optimized sensor placement and circuit design ensure measurement consistency in complex sound fields, making it a reliable tool for engineers, environmental specialists, and facility managers. Its balanced performance in measurement accuracy and operational practicality provides dependable data support for noise control projects.
