Victor VC-824A Digital Sound level Meter Victor Digital Noise Sound Level Meter Decibel 130dB ( VC824A) Condition: New Brand: Victor Model: 824A This digital meter is a multifunction sound level meter designed to accurately measure sound level of just about anything from sound of level of environment to mechanic, vehicle, ship, loudness of computer fans and other noise with ± 1.5 dB accuracy in decibels ( dB) . In almost all countries, the use of A-frequency-weighting is mandated to be used for the protection of workers against noise-induced deafness and the only weighting mandated by the international standard, the frequency weightings ' C' being optional fitments. A precision device that meets the measurement requirements of Safety Engineers, Health, Industrial Safety Offices and Sound Quality control in various environment. Continuous high pressure levels can permanently damage the hearing capacity, even audio speakers. This precision device can help you monitor and maintain healthy environment. SPECIAL FEATURES Measuring Level: 30-130dB ( A) / 35-130dB ( C) Built-in condenser mic Instantaneous sound measure function Two equivalent weighted sound pressure levels, A and C A/ C weighting Fast and Slow dynamic characteristic modes Wide Measuring Range: 30~ 130dB High Accuracy up to ± 1.5dB AC and DC signed output for frequency analyzer level recorder, FFT analyzer, and graphic recorder for data statistical analysis Windscreen for filter-out unwanted signals/ noise Bar graph indication for Sound Level Range Maximum value hold function 4-digit Large LCD screen Tripod mounting SPECIFICATIONS Sound Level: 30 ~ 130 dB w/ level selecting button Level Ranges: 30-80dB, 50-100dB, 60-110dB, 80-130dB Frequency Range: 31.5 Hz to 8.5k Kz Linearity Range: 50dB Measuring Level: 30~ 130dBA, 35~ 130dBC Frequency Weighting: A, C Digital Display: 4 digits Resolution: 0.1dB Analog Bar Graph Self Calibration Time: 3sec Sampling Rate: 2 times/ second Overload indication: Use the symbol OVER and UNDER for indication AC Signal Output: 0.707Vrms/ full bar graph, output impedance is about 600ohm DC Signal Output: 10mV/ dB, output impedance is about 100ohm Dynamic Characteristic ( Time weighting) : FAST ( high speed) / SLOW ( low speed) Microphone: 1/ 2 inch electret condenser microphone Max: Maximum hold Power Supply: 9V alkaline battery or DC 9V 100mA Power adaptor ( not included) Battery life: about 30 hours life span Dimensions: 235 x 70 x 30mm ( LxWxH) Product Weight: approx: 210g Set Contents: 1 x User' s Manual, 9V battery 1 x Sponge Ball Windscreen 1 x Carrying case 1 x VC824A Unit 1 x Data Output cable
