The GA2003 vibration meters is a general purpose pocket sized instrument for industry and the environment that has the capability for taking HARM® measurments (Hand Arm Risk Measurements also known as HAV, Hand Arm Vibration).

Damage to the Hand and Arm through exposure to vibrating hand held power tools is a major area of health and safety risk assessment. Up to now, the process of gathering data to support such a program has been both difficult and costly. The GA2003 answers both of those problems without even having to take a second look. This instrument will simply provide all the data you need to calculate daily exposure for an individual employee.
