30-130dB Noise Meter Display Color Backlit Display Fast Slow Sampling Rate Capacitive Microphone Sound Level Monitor

This noise meter ensures the highest level of accuracy with noise levels ranging from 30 to 130dB, guaranteeing accurate readings every time. The A-weighted and C-weighted mode are designed to mimic the human auditory response, with the A weighting simulating the human ear's response to low-intensity noise, while the C weighting captures the characteristics of high-intensity mechanical noise. This ensures that the readings you receive are consistent with human perception. Suitable for the measurement of environmental noise, such as traffic noise, baby room noise, classroom noise, home theater noise, industrial noise, workshops noise, office areas noise, etc. Features: High Accuracy: This noise meter ensures the highest level of accuracy with noise levels ranging from 30 to 130dB, guaranteeing accurate readings every time. Fast Response: Whether you are monitoring sudden or gradual noise changes, the instrument is ready to meet the demands of a 125 ms fast sampling rate and a 1000 ms slow sampling rate. Reliable Detection Mechanism: Equipped with a 1/2-inch condenser microphone, the unit provides stable, reliable and accurate detection, capturing even the tiniest noise decibels so they don't go unnoticed. Intuitive Display: The backlit color display not only provides clear readings, but also ensures that users can operate the unit in a variety of different lighting conditions. Weighted Mode: The A-weighted and C-weighted mode are designed to mimic the human auditory response, with the A weighting simulating the human ear's response to low-intensity noise, while the C weighting captures the characteristics of high-intensity mechanical noise. This ensures that the readings you receive are consistent with human perception. Automatic Shutdown: Powered by 3*AAA batteries, no need to worry about running out of batteries, it automatically shuts off after 10 minutes of no operation. Multi-field Applications: The dB meter is A-weighted design, which is suitable for the measurement of environmental noise, such as traffic noise, baby room noise, classroom noise, home theater noise, industrial noise, workshops noise, office areas noise, and so forth.  Specifications: Name: Noise Meter Battery: 3 * 1.5V AAA battery (not included) Measure ranges: 30-130dB Sampling rates: 125ms FAST, 1000ms SLOW Frequency response: 31.5Hz-8KHz Resolution: 0.1dB Working conditions: 0-40℃ temperature, ≤80%RH humidity Storage conditions: -20℃ to 60℃ temperature, ≤80%RH humidity Item size: 195 * 73 * 34mm / 7.68 * 2.87 * 1.34in Item weight: 205g / 7.23ounce Package size: 200 * 100 * 50mm / 7.87 * 3.94 * 1.97in Package weight: 230g / 8.11ounce Packing List: 1 * Noise Meter  1 * Screwdriver 1 * Cloth Bag 1 * User Manual
