The SV 104A personal noise dosimeter is designed according to IEC 61252 and ANSI S1.25-1991 (R2020) standards to ensure precise measurements. It complies with occupational noise standards such as ISO 9612, OSHA 29 CFR 1910.95, and MSHA, offering flexibility with exchange rates (2, 3, 4, 5, 6 dB) and criterion levels. The dosimeter can log essential results like TWA (Time-Weighted Average), DOSE, LEX,8H, along with Leq, Peak, SPL, Max, Min, and more.
In addition, it features options for octave band analysis and audio recording for recognizing specific noise sources. Its built-in triaxial vibration sensor helps detect false events caused by shocks or movement, ensuring more accurate readings. The SV 104A’s Bluetooth connectivity allows for remote monitoring, enabling professionals to read out results without disturbing the worker, making it a powerful and convenient tool for managing workplace noise exposure.
-
- The dosimeter is suitable for measurements of noise at work in compliance with standards such as: ISO 9612, OSHA, MSHA and ACGIH.
- The 1/1 octave analysis is often used for the selection of hearing protectors. The 1/3 octave function allows the determination of the influence of high or low frequencies on overall values. Functions are available as firmware options.
- Audio recording is synchronized with a noise time-history and it can be opened and played back in PC software enabling noise source recognition. Audio recording can be triggered on threshold or by time. It can be activated at any time by ordering the activation code.
- The time history logging of results such as Leq, Max, Min and Peak with two simultaneous logging steps is saved on a 8 GB memory.
- The inbuilt triaxial VIBRATION SENSOR detects shocks and vibrations that influence noise measurement results and provides the information during the times when dosimeter is not used by the worker.
- The colour graphical display is an OLED screen with a high contrast visibility even in full daylight or in low ambient light areas.
- The USB interface provides fast data download and is used for battery charging.
