Industrial Application and Logic
In industrial noise monitoring and environmental impact assessments, the integrity of data depends entirely on pre-test and post-test calibration. The AWA 6021A solves the problem of measurement drift in high-precision Class 1 meters used in legal metrology and research. By providing dual output levels (94/114 dB), it allows technicians to verify the linearity of the measurement chain in high-noise environments. The AWA 6022A is optimized for high-volume field use where durability and rapid verification of Class 2 equipment are required for occupational health and safety compliance.
