NL-31精密聲級計產(chǎn)品概述（中文）

NL-31精密聲級計是一款由日本理音（RION）公司設(shè)計生產(chǎn)的高精度噪音測量儀器，適用于環(huán)境監(jiān)測、建筑聲學、工業(yè)機械及室內(nèi)噪音等多種場景的聲學分析需求。該設(shè)備采用緊湊型設(shè)計，整機重量僅400克，便攜性優(yōu)異，配備大型背光液晶顯示屏，支持多參數(shù)同屏顯示。儀器核心功能包括瞬時聲壓級（Lp）、等效連續(xù)聲級（Leq）、最大最小聲級（Lmax/Lmin）及峰值聲級（Lpeak/Lcpeak）等測量，同時支持1/1與1/3倍頻程濾波器擴展分析能力。量程范圍覆蓋28~138dB（A/C計權(quán)），頻率響應(yīng)達20Hz~12.5kHz，滿足寬動態(tài)范圍的測量需求。內(nèi)置數(shù)據(jù)存儲功能可手動保存100組測量數(shù)據(jù)，并可通過RS-232接口實現(xiàn)數(shù)據(jù)導(dǎo)出。儀器采用4節(jié)五號電池供電，續(xù)航時間約27小時，適合長時間戶外作業(yè)。1314

NL-31 Precision Sound Level Meter (English)

The NL-31 Precision Sound Level Meter, manufactured by RION Japan, is a professional-grade acoustic measurement device designed for environmental monitoring, industrial machinery assessment, and architectural acoustics. With a lightweight body of 400g and ergonomic design, it features a high-contrast LCD with backlight for clear data visualization in various lighting conditions. Key measurement capabilities include real-time analysis of Lp, Leq, Lmax/Lmin, and Lpeak/Lcpeak parameters, complemented by optional 1/1 and 1/3 octave band filters for detailed frequency spectrum analysis. The instrument covers a broad measurement range of 28~138dB with A/C weighting, and achieves accurate results across 20Hz~12.5kHz frequency range. Equipped with 100-data manual storage and USB/RS-232 communication interfaces, it facilitates efficient field data collection. Powered by 4 AA batteries delivering up to 27 hours continuous operation, the NL-31 balances portability with robust performance for diverse noise measurement applications.51722

核心功能與技術(shù)特點

該設(shè)備采用數(shù)字信號處理技術(shù)，采樣間隔為30.3微秒，確保高精度瞬時測量。動態(tài)圖表顯示功能可實時呈現(xiàn)聲級變化趨勢，而線性范圍達到100dB無需頻繁切換量程。儀器配置UC-53A型高靈敏度麥克風，配合內(nèi)置電氣校準功能保障長期穩(wěn)定性。用戶可根據(jù)需求同時監(jiān)測多達8項聲學參數(shù)，并利用定時功能實現(xiàn)自動間隔測量（支持10秒至24小時多種時長預(yù)設(shè)）。選購件包括八音度頻帶實時分析卡、延長電纜等，進一步擴展應(yīng)用場景。其防水防塵結(jié)構(gòu)設(shè)計適應(yīng)復(fù)雜環(huán)境，260×76×33mm的緊湊尺寸便于攜帶。91527
