Human Vibration: The Larson Davis HVM 100 is a compact, lightweight hand-held instrument for measuring human exposure to excessive vibration and risk of injury. With Hand-arm and Whole-body modes available, the HVM100 meets the requirements of ISO 5349, ISO 2631, and ISO 8041 and the European Directive 2002/44/EC. It also is ideal for product testing for compliance to ISO 8662.
| - |
Hand-Arm and Whole Body vibration modes for specific applications |
| - |
Measures all three axes of vibration simultaneously |
| - |
Calculates the Vector Sum of the 3 contributing axes |

Dosimeters: Larson Davis produces a family of Personal Noise Dosimeters that provide ease-of-use, compact size and ergonomic design for compliance worldwide noise exposure regulations. They can be supplied with analysis and reporting software and are an important part of any effective Hearing Conservation Program.
Government legislated noise exposure standards require that various exposure metrics are reported, and these can vary by jurisdiction. With user selectable Exchange Rate; Threshold; Criterion Level and Criterion Time the Spark® series of dosimeter ensure you can meet any local requirement for worker exposure reporting compliance.

Calibrators: The essential function to ensure that your Sound Level Meters and Dosimeters are producing accurate and repeatable results is a Larson Davis Sound Calibrator. A specific Sound Calibrator is designed to generate standardized Sound Pressure Levels at specific frequencies when coupled with intended microphone models. The two principal functions of Sound Calibrators are therefore:
| - |
To determine the Elecro-Acoustical sensitivity (transducer performance) of specified microphones |
| - |
To test and calibrate (by adjustment) the overall sensitivity of acoustical measuring systems |
