ENGLISH VERSION:
The AZ8921 Sound Level Meter (RS232) is a professional-grade acoustic measurement instrument designed for environmental noise monitoring, industrial site evaluation, and scientific research applications. Equipped with high-sensitivity sensors and advanced digital processing technology, this device accurately captures sound signals across a broad measurement range while providing real-time data output. Its modular construction combines portability with functional reliability, making it suitable for extended operation in diverse indoor and outdoor environments.
The device features an intelligent data acquisition system capable of automatically recording key parameters including instantaneous sound levels, equivalent continuous sound levels (Leq), and maximum/minimum values. With a measurement range spanning 30dB to 130dB and 0.1dB resolution, it delivers precise acoustic analysis. The integrated RS232 serial communication interface enables bidirectional data transmission with computers, industrial controllers, or data loggers, facilitating the establishment of automated monitoring systems. The backlit LCD display ensures clear visibility in low-light conditions, complemented by practical functions such as data hold and auto power-off.
This instrument finds application across multiple sectors: Environmental protection agencies utilize it for urban noise mapping and construction site compliance monitoring; manufacturing enterprises employ it for equipment noise source identification and occupational health assessments; research institutions leverage its capabilities for acoustic experimentation. The user-friendly interface features three-button navigation for basic configuration, while optional windshields minimize airflow interference during outdoor measurements.
Technical innovations include three key aspects: Precision-maintaining circuit design guarantees measurement accuracy within a wide temperature range (-10℃ to 50℃); advanced RF interference resistance technology enhances data reliability in electromagnetically challenging environments; modular architecture allows flexible combination with various accessories. The rugged engineering plastic housing with ergonomic non-slip grip ensures both durability and operational comfort during extended field use.
