TDJ824支持A/C頻率加權(quán)特性，測(cè)量范圍覆蓋30~130dBA和35~130dBC，動(dòng)態(tài)范圍達(dá)50dB，分辨率精確至0.1dB。設(shè)備具備Fast/Slow動(dòng)態(tài)特性選擇功能，可適應(yīng)穩(wěn)態(tài)與非穩(wěn)態(tài)噪聲的測(cè)量場(chǎng)景。內(nèi)置最大值鎖定功能，便于記錄峰值聲壓級(jí)；低電顯示和過(guò)載提示功能則增強(qiáng)了操作可靠性。4位數(shù)LCD顯示屏（30x50mm）搭配模擬棒條動(dòng)態(tài)顯示，直觀呈現(xiàn)測(cè)量數(shù)據(jù)。3612
技術(shù)參數(shù)與操作特性
該噪音計(jì)采用31.5Hz~8.5kHz寬頻響應(yīng)，取樣頻率為2次/秒，確保高頻信號(hào)的準(zhǔn)確捕捉。供電方式支持6F22 9V堿性電池或電源適配器，工作環(huán)境溫度為0℃~40℃（濕度≤70%RH）。一體式后支架設(shè)計(jì)解放雙手，AC/DC信號(hào)輸出接口便于數(shù)據(jù)外接記錄或分析。自動(dòng)關(guān)機(jī)功能有效延長(zhǎng)電池壽命，符合長(zhǎng)時(shí)間監(jiān)測(cè)需求。3517
應(yīng)用場(chǎng)景
TDJ824廣泛應(yīng)用于建筑工地噪聲監(jiān)測(cè)、工業(yè)生產(chǎn)環(huán)境評(píng)估、車輛噪聲測(cè)試、醫(yī)療機(jī)構(gòu)聲學(xué)環(huán)境檢測(cè)等領(lǐng)域。其便攜性和高精度特性也適用于環(huán)保部門(mén)執(zhí)法檢查、科研機(jī)構(gòu)聲學(xué)研究以及產(chǎn)品質(zhì)量控制等專業(yè)場(chǎng)景。622
Product Overview
The Shenzhen TONDAJ TDJ824 Precision Digital Sound Level Meter (Model: TDJ-824) is a professional-grade acoustic measurement device designed for environmental noise monitoring, industrial noise assessment, and architectural acoustics. Equipped with a high-sensitivity capacitive microphone and digital signal processing technology, it delivers rapid response and accurate sound signal capture. Its compact portable design (235x70x30mm) and lightweight body (approx. 350g) facilitate on-site mobility.359
Key Features
Supporting A/C frequency weighting, the TDJ824 covers measuring ranges of 30~130dBA and 35~130dBC with a 50dB dynamic range and 0.1dB resolution. The Fast/Slow time weighting selection adapts to both steady-state and fluctuating noise scenarios. Features like Max Value Hold, low-battery indication, and overload warning enhance operational reliability. The 4-digit LCD (30x50mm) with analog bar graph provides intuitive data visualization.3612
Technical Specifications
With 31.5Hz~8.5kHz frequency response and 2 times/sec sampling rate, the meter ensures high-frequency signal accuracy. It operates on a 6F22 9V alkaline battery or adapter within 0℃~40℃ (≤70%RH). The integrated rear stand allows hands-free operation, while AC/DC output interfaces enable external data recording. Auto power-off function optimizes battery efficiency for prolonged monitoring.3517
Applications
Ideal for construction site monitoring, industrial noise evaluation, vehicle acoustic testing, and healthcare facility assessments, its portability and precision also serve environmental law enforcement, academic research, and product quality control.622
