Key features

• •【High Accuracy】Mastfuyi decibel meter uses a precise condenser microphone to capture sound, measures sound level 30-130 dBA, 35-130dBC. Highly accurate with ±1.5 dB, Frequency from 30Hz to 8,000KHz, Perfect for monitoring noise levels in community, home, audio system, automobile, school, office, factory
• •【A/C Weighted Measurement】When measuring the sound level felt by human beings, select A-Weighting mode which simulates the frequency of low-intensity human ear noise; when measuring the actual sound level like noise analysis of machine motors and machines, select C-Weighting mode which simulates the frequency of high-intensity noises of the human ear. Professional measurement methods provide users with a perfect experience
• •【Compact and Lightweight】Composite material injection molding process and ergonomic design, non-slip and wear-resistant, comfortable to hold; Slim and lightweight, doesn't take up space, easy to carry and store; Pocket clip design allows it to be securely clipped to the pocket and not easily dropped and lost
• •【Fast/Slow Measurement】The Fast-Weighting mode uses a constant of 0.125s/time, which is suitable for measuring the sound level in real time in general environment; The Slow-Weighting mode uses a 1s/time constant, which is suitable for environmental measurements with relatively large changes in noise levels
• •【Versatile Uses】Features a full color LCD screen with a resolution of 0.1 dB, clear and beautiful; MAX hold function to lock the maximum value; Auto power off after 15 minutes inactivity to prolong battery lifespan; Data Hold function to freeze the current readout, easy to read and record data; Flashlight for use at night
• •【Dual Visual Alerts】Level 1 (90dB): 🟩🟨🟥 analog bars is displayed, 🔴 indicator lights up, need to leave the sound source as soon as possible
