【English Version】
The NA-42 Precision Wide-Range Noise Analyzer is a professional measurement device specifically designed for complex acoustic environments, applicable to industrial manufacturing, environmental monitoring, architectural acoustics and other fields. Utilizing advanced digital signal processing technology, this instrument achieves accurate sound pressure level measurements within the range of 20dB to 140dB, with its wide measurement capacity accommodating various scenarios from quiet laboratories to heavy machinery plants.
Equipped with a proprietary multi-band analysis module, the device supports real-time 1/1 octave and 1/3 octave analysis, enabling in-depth noise spectrum decomposition. The high-sensitivity condenser microphone sensor effectively minimizes the impact of ambient temperature and humidity variations on measurement results, maintaining ±0.5dB accuracy within operating temperatures from -10℃ to 50℃.
Featuring a 3.5-inch high-resolution color display, the analyzer provides dual-mode waveform and numerical readouts. With 32GB built-in storage capacity, it can continuously record measurement data for over 200 hours, supporting fast data transfer via USB-C interface. The modular design optimizes field operation convenience, with the main unit weighing 580 grams and supporting 12-hour continuous operation through replaceable lithium battery packs.
The accompanying acoustic analysis software offers time-domain analysis, FFT spectrum analysis, and statistical reporting functions, compatible with both Windows and MacOS systems. Enhanced electromagnetic interference resistance ensures stable performance in strong electromagnetic environments, making it suitable for long-term monitoring in power substations, rail transit systems and other specialized applications.
