New 7 Range Sound Level Audio Noise Meter Decible DB NEW 7 Range Sound Level Audio Noise Meter Decible DB New with Analog Display Measurment DB This is a Brand New Sound Level Pressure Meter which is useful for measuring sound intensity, determining speaker efficency or developing quick frequency response plots for loudspeakers.  Power is supplied by a 9-volt battery, so the meter is completely portable. To create quick frequency response plots, use an Audio Test CD and read the sound pressure directly from the meter. You can search for a free Audio Test CD on the Interner. For more detailed plots, you can use a wide variety of commerical and free software.  You can also search for  a Free Frequency Response Plotter Software with built in corrections for the meter on the Internet. For more accurate results while testing loudspeakers, it is best to do the measurements outdoors in a quiet and spacious area. Your sound level meter is an extremely versatile device for measuring sound intensity in just about any acoustic environment-loud or soft: high-pitched, lowpitched, or broad-band; intermittent or continuous. You can use it to measure noise levels in factories, schools, offices, and airports, or to check acoustics of studios, auditoriums, and home theater installations. Your meter features a large, easy-to-read indicator for taking quick measurements anywhere. Power is supplied by a 9-volt rectangular battery, so the meter is completely portable.   Features: Seven sound-level ranges:allow measurements from 50---126 DB. A and C weightings:lets you check compliance with safety regulations as well as make acoustic analysis. Slow and fast response settings:let you check peak and average noise levels. Builtin battery condition indicator. Phono-type output jack:for connection to home theater or test equipment. 60 dB: 50 TO 66 dB 70 dB: 60 TO 76 dB 80 dB: 70 to 86 dB 90 dB: 80 to 96 dB 100 dB: 90 to 106 dB 110 dB: 100 to 116 dB 120 dB: 110 to 126 dB Accuracy: +/- 2 dB @ 114 dB Standard: 0 dB = 0.0002 u bar Signal Output: 1.0 volt (peak) minimum into open circuit,with full scale meter deflection at 1 kHz Load Impedance: 10 kOhms minimum Distortion: Less than 2% at 1 kHz, 0.5-volt Microphone: Electric condenser; omnidirectional Size (HWD): 6-5/16 x 2-7/16 x 1-3/4 Inches (160 x 62 x 44 mm) Weight: 6.6 oz (about 185 grams) Specification: Switch Setting Range 60dB 50-66dB 70dB 60-76dB 80dB 70-86dB 90dB 80-96dB 100dB 90-106dB 110dB 100-116dB 120dB 110-126dB   Accuracy ..........±2dB@114dB Standard ..........0 dB = 0.0002μbar Weighting..........A and C Response...........Fast and slow Signal Output......1.0 volt(peak) minimum into open circuit, with full-scale meter deflection at 1 kHz Load Impedance.....10 kohm minimum Distortion ........Less than 2%at 1 kHz 0.5-Volt Microphone.........Electret condenser omnidirectinal becoming slightly directional with increase in frequency Battery............One 9-volt rectangual type supplied   Summary of My Selling Policies Payment We accept Pay pal.
