The Amprobe SM-10 type 2 sound meter measures sound pressure levels (spl) in environmental quality control and acoustic analysis applications, such as when checking compliance with noise pollution regulations and health and safety codes. It has two measurement settings. The “A†weighting is for taking measurements where there is low to moderate ambient noise, such as in an office. The “C†weighting is for taking measurements where there is loud low-frequency background noise, such as in machine shops. The meter offers a choice of two response speeds. The fast 125-millisecond response setting measures the average sound level in environments with steady ambient sound, and the slow 1-second response setting measures peak noise levels in environments with fluctuating ambient sound. The 1/2-inch condenser microphone comes with a windscreen to shield the microphone in outdoor conditions with wind speeds over 10 m/sec (22.3 mph). The maximum or minimum reading mode displays the highest or lowest reading in a session to track sudden increases or decreases in measurements. The data hold function keeps a reading on the display even after the meter is disconnected or the measurement changes. The meter's backlit liquid crystal display (LCD) is readable in low light and shows measurements in 0.1 dB increments up to 4 digits. The auto-power off function turns off the unit after 5 minutes of non-use to conserve battery life.Specifications Frequency range 31.5 hertz (Hz) to 8 kilohertz (KHz) Sound level measurement range, “A†weighting 30 to 130 decibels (dB) Sound level measurement range, “C†weighting 35 to 130 dB Dynamic range 50 dB Power supply 9V NEDA 1604, IEC 6F22, or JIS 006P battery (one, installed) Standards met International Electrotechnical Commission (IEC); American National Standards Institute (ANSI); Japanese Industrial Standards Commission (JISC); European Conformity (CE); N10140 Australian Weight 0.5 lb./233 g Meter dimensions 7.8 x 2.2 x 1.5 inche...
