Info Produk
The Amprobe SM-20-A Sound Level Meter has been designed to meet the measurement requirements of safety Engineers, Health, Industrial safety offices and quality control in various environments. 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.
