Personal noise dosimeter

SV 104A

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.

Noise Dosimeter App: Real-Time Noise Monitoring

The Noise Dosimeter App allows users to seamlessly monitor real-time noise measurements from their wearable dosimeter directly on a smartphone or tablet. This companion tool provides a convenient, remote way to view data without needing to physically interact with the device, making it easier to manage workplace noise exposure. While the app doesn’t perform measurements itself, it displays accurate data collected by the professional-grade dosimeter. Users can also set alarms for when noise exceeds safe levels and control the dosimeter remotely, enhancing efficiency and safety without compromising measurement precision.

Frequency Analysis and Audio Recording

Enhanced Noise Source Identification

Identify and analyze noise sources with the SV 104A noise dosimeter's advanced options for audio recording, frequency analysis, and motion detection. This dosimeter performs unattended measurements, but as it is worn by workers, accidental drops or removal can occur. The built-in octave analysis and vibration detection help detect and exclude such artifacts from the data, ensuring more accurate results. Additionally, the audio recording feature allows for identifying unwanted noise sources, like background music, that are unrelated to the work environment.

Bluetooth App

Remote Control and Real-Time Monitoring

The SV 104A’s Bluetooth® interface allows for remote control and live monitoring of noise measurements. Using the ASSISTANT PRO app on a smartphone or tablet, professionals can easily start or stop measurements and view real-time results without needing to handle the device directly. The app also triggers an alarm if preset noise limits are exceeded, ensuring immediate awareness and action when necessary.

Auto-Calibration

Simplifying Accurate Measurements

The SV 104A features an auto-calibration function that automatically detects a calibration signal and initiates the calibration process. This eliminates the need for manual calibration, making noise dosimetry easier and more efficient. The device saves calibration data both before and after measurements, ensuring accuracy and traceability in your noise exposure assessments.

Inbuilt Vibration Sensor

Ensuring Accurate Noise Measurement

The SV 104A is equipped with an inbuilt tri-axial vibration sensor that detects mechanical shocks and vibrations affecting noise measurements. This sensor identifies moments when the dosimeter is not being used properly, such as when dropped or mishandled. These incidents are marked in the time history, allowing professionals to easily exclude inaccurate data from the dose calculation, ensuring more reliable and precise results.

Occupational Noise

Noise Measurements for Regulatory Compliance

The SV 104A personal noise dosimeter is designed for occupational noise measurements in accordance with standards such as ISO 9612, OSHA 29 CFR 1910.95, MSHA, and ACGIH. It ensures compliance with OSHA's noise exposure regulations, which define permissible noise limits and outline the requirements for hearing conservation programs. The dosimeter accurately measures personal noise exposure levels, including the 8-hour Time-Weighted Average (TWA) of 90 dBA and the action level of 85 dBA, helping companies assess noise risks and implement effective hearing conservation measures. This makes the SV 104A an essential tool for ensuring workplace safety and maintaining regulatory compliance.
