What is the ST-130 Noise Dosimeter and what is it used for?
ST-130 Noise Dosimeter is a wearable acoustic measurement device designed to monitor individual noise exposure over time. It is primarily used in occupational safety, industrial hygiene, and compliance testing to assess worker exposure to hazardous noise levels.
How is a noise dosimeter different from a sound level meter?
A sound level meter measures noise at a specific location, whereas a noise dosimeter measures personal exposure over a full work shift (typically 8 hours). It tracks cumulative noise dose and provides metrics like TWA (Time Weighted Average) and %Dose, which are critical for workplace safety compliance.
What standards does the ST-130 comply with?
The ST-130 complies with major international standards including OSHA, IEC, ISO, MSHA, ACGIH, and DOD, making it suitable for regulatory and industrial compliance applications.
What are the key measurement capabilities of the ST-130?
The device measures a comprehensive set of parameters such as:
- Noise dose (%Dose), TWA, Leq, SEL, Peak levels
- Statistical values like Ln% (L10, L50, L90)
- Frequency weightings (A, C, Z) and time weightings (Fast, Slow, Impulse)
It also supports dual modes: Noise Dosimeter Mode and Sound Level Meter Mode.
What makes ST-130 suitable for real-world industrial use?
Key advantages include:
- Lightweight, wearable, cable-free design for all-day monitoring
- Up to 24-hour battery life and large internal memory (up to 1,000,000 readings)
- USB connectivity with PC software for data download and reporting
- Ideal for industries like construction, mining, oil & gas, and manufacturing
