It offers two types of measurements: A weighting and C weight. The A weighting is for general noise sound level and the C weighting is for measuring sound level of acoustic material control in various environments ( ie 94dB 1 kHz etc...) . The SM-20-A conforms to the IEC651 Type 2, ANSI S1.4 Type 2, and JISC1502 requirements for Sound Level Meters. Which means the SM-20-A uses two different weighting filters required by the IEC 651 and ANSI S1.4 Type 2: The A-Weighting and the C-Weighting audio filtering. Features Designed to meet the measurement requirements of Safety Engineers, Health, Industrial safety offices and quality control in various environments. A and C weightings for checking compliance with safety regulations as well as acoustic analysis Measuring ranges: A Weighting 30~ 130dB, C Weighting 35~ 130dB Frequency range: 31.5Hz~ 8KHz Display with 0.1dB steps on a 4 digit LCD Slow ( 1 sec) and fast ( 125ms) response settings to check peak and average noise levels MAX/ MIN recording Internal memory, 14, 000 records Recording intervals from 1 second to 8 hours PC computer download capabilities Data Hold to freeze reading on digital display CE, designed to meet IEC651 Type2, ANSI S1.4 Type2
