About Amprobe SM-10 Sound Level Meter
The Amprobe SM-10 Sound Meter has been designed to check compliance with safety regulations and perform acoustic analysis by safety engineers, health, industrial and safety offices as well as quality control. They use two different weighting filters required by the IEC651 and ANSI S1.4 Type 2 for audio filtering. 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.) 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 digits LCD Slow (1 sec) and fast (125ms) response settings to check peak and average noise levels Max/min recording Data Hold to freeze reading on digital display Accessories supplied: carrying case, windscreen, user manual and 9V battery CE, designed to meet IEC651 type2, ANSI S1.4 type2 Features SM-10 SM-20A Microphone 1/2 Electret condenser microphone Standard applied IEC 651 Type 2, ANSI 1.4 Type 2 Dynamic range 50 dB Time weighting FAST (125 mS), SLOW (1 sec) Frequency range 31.5 Hz → 8 kHz Measuring level range (Auto Range) A-Weighting: 30 dB → 130 dB C-Weighting: 35 dB → 130 dB Data Data hold Min/max Internal memory - 14, 000 records Specifications Display: 4 digits LCD Microphone: 1/2 inch electret condenser microphone Power supply: 9V NEDA 1604, IEC 6F22, JIS 006P battery Auto power off: Approx. 5 min Environment: Indoor operation, < 2000 m Standard applied: IEC 651 Type 2, ANSI 1.4 Type 2 Dynamic range: 50 dB Resolution: 0.1 dB, Display update: 0.5 sec.
