    Product Description

    Integrating Precision Sound Level Meter (Castle 6224)

    Measuring noise really does not have to be complicated, even for the novice, and the Castle 6224 (Class 1). Integrating sound level meter is designed with this in mind.

    The meter is ideally equipped for carrying out Noise at Work Risk Assessments, as well as the majority of environmental survey work. The range of parameters measured, the wide measuring capability of the meter and the ease of use, mean that this equipment is suitable for anything from aircraft noise to lawnmower design, and from construction sites to laboratories.


    • Equivalent continuous level (Leq)

    • 5 user selectable percentile values (Ln)

    • Wide Linearity range of 90dB

    • RS232 for data output to optional software

    • Memory storage for 10,000 datapoints

    • Back-lit LCD display
