Class 2 Dual-Channel Noise Dosimeter
The Class 2 Dual-Channel Noise Dosimeter is designed for accurate measurement of noise exposure, adhering to ISO 9612 and MIRE (Microphone in Real Ear) measurement standards (ISO 11904-1). It offers advanced features like 1/3 octave analysis and dual-channel noise measurement, making it ideal for environments where noise exposure may come from multiple directions or specific sources such as headphones. This dosimeter is perfect for applications where traditional dosimetry methods are ineffective, such as in call centers or environments with close-ear sound sources.
Features a high-resolution OLED display, allowing easy readability even in bright daylight. It also boasts a large memory capacity, upgraded with a microSD card, providing ample storage for data. The device’s dual-channel measurement capability ensures accurate assessment of noise exposure from both sides of the head or inside and outside hearing protection. Additionally, it features a built-in frequency analyzer and supports audio recording, enabling precise analysis and eliminating false readings caused by background sounds. Key Features: |
