Decibel Meter, VLIKE Sound Level Meter dB Meter Measuring from 30 dB to 130 dB with A​/​C Mode VLIKE Digital Sound Level Meter​/​Decibel Meter​/​dB Meter​/​Noise Meter Wherever you need to monitor sound levels, VLIKE Sound Level Meter will do the job. The meter utilizes a 1​/​2-inch electric condenser microphone to monitor sound levels from 30 to 130 decibels at an accuracy of +​/​-1.5 dB with a 0.1 dB resolution. A windscreen is included to prevent distortion in the readings. The VLIKE Sound Meter weighs less than 6.7 ounces, and is designed to fit comfortably in the palm of your hand. Choose between either A or C weighting, auto or manual ranging, records max​/​min values over time. Other useful features include auto power-off, max hold functions, and fast​/​slow response time. Record sound values over time to track sound changes. The large LCD display gives readings in large, clear numbers. it shows the sound level readings using a fast-responding analog bar graph with a 50-decibel range that updates every 40 milliseconds for viewing varying trends. Wide Application Whether you’re the sound mixing wizard for a rock concert, or a road traffic controller, or simply just looking for a solid sound measurement equipment, this sound level meter tester is one tool you want to add into your magic toolbox. The Decibel Meter lets you know if you’re being exposed to dangerously high frequencies, and make it easy for you to jot down sound frequencies for future reference. And with simple intuitive buttons, like the backlight LCD display and manual​/​auto shutoff function, we make this decibel meter reader’s navigation stress-free, so you can block out the background noise and focus on the bigger things. Package Included 1 * Sound Level Meter(Batteries not include) 1 * User Manual 1 * Black case bag Warm Prompt 1.Do not use the meter in hot,humid environment. 2.If the meter is not to be used for a long time, remove the batteries to avoid electrolyte leakage damaging instrument. 3. When measuring the noise outside, please mount the wind-resistant ball on the head of the microphone from being directly blown by wind and measuring other noise. 4. Normally you don’t need to calibrate it because it was calibrated before delivery.If you want to calibrate it, it needs Primary standard acoustic source, acoustic environment,we suggest only professional engineers ,the third testing organization or the credited laboratory could to calibrate the meter. VLIKE Digital Sound Level Meter complies with IEC651 type 2 and ANSI S1.4 type 2. It also could be called as DB reader, phonometer or SPL meter,accumulate sound level value data for noise dosimeter, can be used as a noise monitor testing sound intensity to reduce Noise pollution, avoiding the risk to hearing damage. But it is account for the relative loudness perceived by the human ear.The value will fluctuate according to the different distance sound source. Whether you're monitoring workplace machinery, installing audio or alarm systems, or handling product noise certification and reduction, VLIKE Digital Sound Level Meter gets the job done. There are two weighting modes for it, A and C frequency-weighting mode, there is a A​/​C key press for selection. A is for measuring the sound level within the human audible range, the test range is 30-130 dBA, it’s used for the protection of workers against noise-induced hearing loss. And C is for measuring the actual sound level, which can be sensitive to the higher frequencies human couldn’t hear, the C weighting is most meaningful for describing the frequency response of real world sounds. And it’s test range is 35-130 dBC. But we are more sensitive to the lower frequencies, so if we use C weighting, the sound level will be higher than acoustic sound.
