When using the Assessor Models 81A or 82A, Industrial Noise Integrating Sound Level Meter, making a measurement couldn’t be easier; simply switch the unit on and the instrument starts measuring. To complete the measurement, press the ‘Stop’ button and everything needed for your assessment is displayed on one screen.
The ‘A’ weighted Leq or average noise level is displayed along with the ‘C’ weighted Peak value, which is used for the assessment of impulsive noise sources.
All of the Assessor instruments have a unique display showing the estimated exposure duration. This feature estimates the noise exposure that would be achieved if the measurement was made over a longer period displayed in terms of LEX,8.
