<p>1. High precision: Using a capacitive microphone, the measurement range can reach 30-130dB, and the noise accuracy is \u00B1 2.0d, helping you accurately capture the decibels of noise;</p> <p>2. Adjustable fast and slow modes: Fast and slow mode time weighting, fast mode can reach up to 125ms per second, slow mode can reach up to 1000ms per second;</p> <p>3. MAX value reset: After measurement, the maximum value can be automatically locked and reset by short pressing, making it easy to use;</p> <p>4. Sponge ball protective cover: An external sponge ball protective cover can the accuracy of within a certain wind speed range and also provide protection for the microphone;</p> <p>5. Humanized design, widely used: Both sides are made of soft rubber material, providing a comfortable grip. It can also be applied to scenarios such as offices, libraries, car noise, program , factory equipment, etc.</p> <p>Product Name: High precision noise detector</p> <p>Measurement range: 30dB-130dB</p> <p>Sampling rate FAST: 125ms</p> <p>Sampling rate SLOW: 1000ms</p> <p>Noise accuracy: \u00B1 2.0dB</p> <p>Reference sound pressure standard: 94dB\/1KHz</p> <p>Frequency response: 31.5Hz-8KHz</p> <p>Resolution: 0.1dB</p> <p>Power supply: 2 x AAA batteries(not included)</p> <p>Working current:\u22648mA</p> <p>Working temperature: 0\u00B0C-40\u00B0C</p> <p>Working humidity: \u226480% RH</p> <p>Storage temperature: -20\u00B0C-60\u00B0C</p> <p>Storage humidity:\u226475% RH</p> <p>Due to different factory batches, the product words are different, and the product accessories have slight differences in color and appearance, but it does not affect normal use</p> <p>Colour:As Shown</p> <p>Material:ABS</p> <p>Package Contents:</p> <p>1set x noise meter decibel detector</p> <p>Only the above package content, other products are not included.</p> <p>Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
