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
