【English Product Introduction】
The Sima series noise measurement devices are precision acoustic analysis tools designed for environmental monitoring, industrial inspection, and daily life applications. Utilizing advanced digital sensing technology, these instruments can detect sound vibrations within 20Hz to 12.5kHz range with ±1.5dB accuracy, adapting to diverse environmental sound level monitoring requirements. The backlit LCD screen enables clear data reading in dim environments, featuring real-time dynamic display and value hold functions for enhanced operational convenience.
An intelligent auto-ranging system automatically selects optimal detection ranges according to ambient noise intensity, eliminating manual adjustment errors. The built-in memory module stores 200 measurement datasets, with USB export capability supporting long-term trend analysis and report generation. The portable housing with anti-slip rubber coating ensures secure grip and impact resistance, making it ideal for mobile detection tasks at construction sites, transportation hubs, and residential areas.
Equipped with professional-grade capacitor microphones, the devices minimize measurement interference caused by temperature and humidity variations. The rechargeable lithium battery provides 30-hour continuous operation, complemented by Type-C fast charging. The user-friendly interface incorporates threshold alert functionality, triggering audible and visual warnings when environmental noise exceeds preset levels, delivering immediate feedback for noise management in manufacturing plants, office spaces, and educational institutions.
