CEL-254 Pulsed Sound Level Meter (English Introduction)
The CEL-254 is a professional-grade sound level meter designed for versatile noise measurement applications. It features a 1/4-inch electret microphone with dual-range capability (30-100dB and 65-135dB), enabling accurate monitoring of transient sound levels. The instrument supports A/C frequency weighting and offers slow/fast/impulse time weighting modes, along with peak hold function for capturing short-duration impact sounds. Equipped with a 12.7mm large LCD display (0.1dB resolution), it provides clear readouts in varying environments. The compact body (258×70×21mm) houses 4×AAA alkaline batteries for 20 hours continuous operation, while AC/DC outputs facilitate data recording. Ideal for industrial safety and environmental monitoring, its ergonomic design ensures portability without compromising measurement stability. 91416
核心功能特點(diǎn)（中文）
該設(shè)備的最大值保持功能可鎖定噪聲源的峰值聲壓級(jí)，特別適用于機(jī)械沖擊聲、爆炸聲等瞬態(tài)噪聲測(cè)量。儀器采用兩鍵式操作設(shè)計(jì)，簡化了復(fù)雜環(huán)境下的使用流程。內(nèi)部數(shù)字信號(hào)處理技術(shù)保障了測(cè)量數(shù)據(jù)的可靠性，濕度補(bǔ)償功能（30%-90%RH范圍影響≤0.5dB）增強(qiáng)了環(huán)境適應(yīng)性。標(biāo)準(zhǔn)配置包含主機(jī)、聲校準(zhǔn)器、防風(fēng)球及便攜箱，滿足即用型需求。其寬溫工作范圍（-10℃~+50℃）與堅(jiān)固結(jié)構(gòu)，適應(yīng)戶外長時(shí)間作業(yè)。1410
Key Performance Highlights (English)
The CEL-254 distinguishes itself with advanced pulse detection capability, capturing transient noises like mechanical impacts or gunshots via its max hold function. The intuitive two-button interface reduces operational complexity during field measurements. Digital signal processing technology ensures consistent accuracy across a 70dB dynamic range, with automatic humidity compensation (≤0.5dB deviation). The package includes a carrying case with windshield and acoustic calibrator for immediate deployment. With rugged construction and extended temperature tolerance (-20℃~+60℃ storage range), it delivers stable performance in harsh conditions. The lightweight design (230g with batteries) balances durability and mobility for diverse measurement scenarios. 121317
應(yīng)用場景說明（中文）
該產(chǎn)品廣泛應(yīng)用于工廠設(shè)備噪聲診斷、建筑工地脈沖噪聲監(jiān)測(cè)、交通運(yùn)輸噪聲評(píng)估等場景。在職業(yè)衛(wèi)生領(lǐng)域，可量化工作人員噪聲暴露水平；在環(huán)保監(jiān)測(cè)中，能記錄突發(fā)性噪聲事件數(shù)據(jù)。其實(shí)時(shí)顯示功能支持快速判斷噪聲源特性，而模擬輸出接口便于連接記錄設(shè)備進(jìn)行長期分析。適用于需要兼顧穩(wěn)態(tài)與瞬態(tài)噪聲測(cè)量的復(fù)合型場景，如沖壓車間、發(fā)電廠或市政工程現(xiàn)場。81118
Typical Applications (English)
This meter serves critical roles in industrial machinery maintenance (e.g., press shops, power plants), construction site noise control, and traffic noise mapping. For occupational health surveys, it quantifies workers noise exposure with pulse-weighted measurements. Environmental specialists utilize its transient capture mode for event-based monitoring like fireworks or demolition noises. The real-time display with analog outputs enables both quick assessments and extended logging via external recorders. Its versatility makes it suitable for hybrid environments requiring simultaneous steady-state and impulsive noise analysis, such as manufacturing facilities with intermittent equipment operations. 3715
