GoerTek purchase a standard LB-808 multifunction integrating sound level meter

LB-808 multi-functional Sound Level Meter Overview: LB-808 multi-purpose sound level meter large LCD display, with streamlined body design and good ergonomics, and acoustic measurements for the optimized use of The latest ARM chip as the core of computing and processing. It uses patented digital detection technology, wide linear range level measurement process without switching range, easy to use. Modular design, including integrating sound level meter, personal sound exposure meter, noise statistics analyzer functions. External micro-printer (optional) can be printed on-site measurements. The instrument can be widely applied in the fields of environmental protection, labor and health, industrial enterprises, scientific research and teaching, environmental noise measurement, sound power level measurement, noise measurement equipment, environmental noise monitoring is the most commonly used instrument. Product Features 1. Can the noise level and the sound level meter display operating status, time, temperature, power and other information, dynamic spokes can be more intuitive display noise value change; 2. All digital processing can produce three sets of data, each The frequency weighting A, C, Z, time weighting F, S, I and SPL, RMS, PEAK, LEQ, MAX can be any combination; 3. Statistical analysis can display statistics percentage value of 10 groups set arbitrarily set range from L1 to L99; 4. time course interface can display one minute -10 minute time domain noise curve for the analysis of noise distribution, trends and real-time noise events; 5. octave interface can display 1/1 times The five groups octave bands and total sound pressure level, according to GB22337-2008 in the "structure-borne noise emission limits for indoor fixture" excessive frequency automatic alarm display, according to the situation of excessive automatically determine whether the fixed structure-borne noise generated by the equipment. 6 Chinese and English menu optional LB- 808 I-class sound level meter standard IEC 616 721 level, type IEC60651 1, IEC60804 1 type GB / T grade 3785 1, GB / T grade 17181 1 GB / T 3241 (IEC61260) 1 Standard microphone 1/2 inch pre-polarized measurement microphones measure LXY (SPL), LX (RMS), LXeq, LXYmax, LXYmin, LXPeak, LXN, SD, SEL. Where X = A, C, Z, Y = F, S, I, N = 1-99 arbitrarily set integration time manually, 10s 1min 5min 10min 20min 1h 2h 4h 8h 24h 24 automatic measurements measured in hours, a group of data stored per second the SD card frequency / time weighting A, C, Z / F, S, I, Peak octave analysis according to GB22337 standard five octave: 31.5 Hz, 63 Hz, 125 Hz, 250 Hz, 500Hz this Noise 14 dB (A), 17dB (C), 23dB (z) Accuracy 0.1dB measurement limit 130dB or 160dB (custom) response / dynamic range 10-20000Hz / 101 dB (A) range setting automatic, manually adjustable high-precision 24 bit AD sampling frequency of 48KHz analysis rate 61 times / second image display 160x160 dot matrix LCD with backlight, adjustable contrast 4G SD memory card standard, large-capacity storage output AC and DC (10mV / dB) , RS-232 alarm can be set Alarming supply four AA alkaline batteries, the sustainable use of more than 16h, also be an external 8-14V power supply Operating ambient temperature -10 ℃ ~ 50 ℃, humidity 10% -95% RH ( no condensation) Dimensions / Weight 298 x 70 x35 mm / about 0.45kg Optional Printer Thermal printer optional extension cable 5m, 10m, 50m microphone extension cable to the host reads the data processing software optional SD card, the analysis results , database management and report generation Qingdao Lu Bo provide the comprehensive technical support and after-sales service!
