The Tenmars ST-130 Noise Dose Meter (dosimeter) is a specialised Sound Level Meter that is designed to measure the noise exposure that a person has been subject to over a period of time; the measurement are normally performed in order to meet current Health and Safety regulations. Noise dose meters are also referred to as personal noise dosimeters or personal dosimeters. With six built-in standard dose measurement setups (OSHA, MSHA, DOD, ACGIH, ISO85, ISO90), the Tenmars ST-130 Noise Dose Meter is the ideal instrument for performing OSHA and IEC Noise accumulation surveys. This noise dosimeter comes with a USB download cable and CD software for downloading the measured data. The meter can also be used in SLM (Sound Level meter Mode) Tenmars ST-130 Noise Dose Meter Applications: Evaluation of environmental noise Measurements of noise at workplaces, Assessment of product noise.
