Personal noise dosimeter

The Personal Noise Dosimeter is a high-precision, occupational noise measurement tool, designed to comply with industry standards like IEC 61252, ANSI S1.25-1991 (R2020), and ISO 9612. It allows for detailed noise exposure tracking and includes features such as TWA, DOSE, Leq, Peak, and more. This device ensures accurate readings and is equipped with a built-in triaxial vibration sensor to detect false events caused by shocks or movement, providing reliability in demanding environments. Key Features: Compliance with Industry Standards: Meets IEC 61252, ANSI S1.25-1991 (R2020), ISO 9612, and OSHA standards for occupational noise monitoring. Flexible Exchange Rates: Allows for exchange rates of 2, 3, 4, 5, 6 dB and customizable criterion levels for enhanced adaptability. Comprehensive Noise Logging: Logs essential noise metrics, including TWA, DOSE, LEX,8H, Leq, Peak, SPL, Max, and Min for comprehensive exposure analysis. Octave Band Analysis & Audio Recording: Offers the option for detailed noise source analysis and audio recording, providing more context for noise measurements. Bluetooth Connectivity: Enables remote monitoring and reading of results, enhancing workflow without disturbing workers. Vibration Sensor for Accurate Measurements: Built-in triaxial vibration sensor detects false events caused by shocks or movement. Durable MEMS Microphone Technology: Superior durability, shock-resistance, and low power consumption to enhance device reliability and battery life.
