Tenmars ST-130 Noise Dosimeter (also called Dose Meter) is a specialized 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 is normally performed in order to meet current Health and Safety regulations.

With six built-in standard dose measurement setups (OSHA, MSHA, DOD, ACGIH, ISO85, ISO90), the Tenmars ST-130 Noise Dosimeter is the ideal instrument for performing OSHA and IEC Noise accumulation surveys. 

Noise dose meters are also referred to as personal noise dosimeters or personal dosimeters. Comes with 2 Modes, Noise Dosimeter Mode (NDM) & Sound Level Meter Mode (SLM). The meter works in one mode at a time. SLM mode has data logging feature that can record up to 10000 readings which can be downloaded to a PC for further analysis via the built-in USB interface. 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).

Provide fast and easy on-site surveys to help determine noise reduction requirements.
