DIGITAL NOISE SOUND LEVEL DB METER DECIBEL IN DURBAN

Digital Noise Sound Level dB Meter Decibel This digital meter is a multifunction sound level meter designed to accurately measure environmental noise, such as the noise from mechanic, vehicle, ship, loudness of computer fans and other noise with +-2 dB accuracy in decibels (dB). This unit was designed according to the IEC651 TYPER2 & ANSI S1.4 TYPE2 for sound level meters. Instantaneous sound measure function. With two equivalent weighted sound pressure levels, A and C. Fast & Slow dynamic characteristic modes. AC and DC signed output for frequency analyzer level recorder, FFT analyzer, graphic recorder etc. Features: * Conformed to the IEC 651 Type 2 and ANSI S1.4 Type 2 set standard * Wide Measuring Range: dB * With 2 equivalent weighted sound pressure levels A and C * Fast and Slow dynamic characteristic modes * Bar graph indication for Sound Level Range * Maximum hold function * Large LCD screen with 4 digits reading * MAX/MIN quasi-analog bar indicator * Fast & Slow response selectable * Low battery indicator * * * Monitor the sound levels from traffic noise, alarm systems and workplace machinery Specification: * Accuracy: +-2 dB * Frequency Range: 31.5 Hz to 8.5k Hz * Linearity Range: 50dB * Measuring Level: dBA, dBC * Frequency Weighting: A, C * Digital Display: 4 digits * Resolution: 0.1dB * Display: 0.5 secretary * Analog Bar Graph: 50dB scale at 1dB step for monitoring current sound pressure level display period of 50mS * Overload indication: Under indicate less than lower limit of the range * AC output: Vrms at FS output impedance approx 600 * DC output: 10 mV / dB output impedance approx 100 * Dynamic Characteristic (Time weighting): FAST (high speed) / SLOW (low speed) * Microphone: 1/2 inch electret condenser microphone * Max: Maximum hold * Power Supply: 9V 6F22 battery(not included) or DC 9V 100mA * Operating Environment: 0¿¿C to 40¿¿C, 10% to 70% RH * Storage Environment: -10¿¿C to 50¿¿C, 10% to 80% RH * Dimensions: 235 x 70 x 30 mm (LxWxH)   rrd
