FY8837 Decibel Meter with A/C Weighted, Digital Sound Level

Sound level meter is a instrument which used to measure the environmental sound level : such as sound level in factories, workshops, schools, home, workplaces, traffic, audio and other occasions. It is also suitable for noise engineering, product quality control, health prevention and control



Features:

【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.

【High Accuracy】The 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 8KHz, Perfect for monitoring noise levels in community, home, audio system, automobile, school, office, factory.

【/Slow Measurement】The -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.

【Compact and Lightweight】Shell using composite material injection molding process, anti-drop structure design, not only solid wear-resistant, but also beautiful and 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.

【LCD Color Display】Features a full color LCD screen with a resolution of 0.1 dB, clear and beautiful; A sound level analog bar is displayed on the screen, and it's equipped with a sound level indicator light as dual visual alerts; Digital display, with advantages of good anti-interference performance and saving. A battery indicator will appear on the screen when the battery is low to remind the user to replace the batteries in time.

【Versatile Uses】MAX hold function to lock the maximum value; Auto off after 15 minutes inactivity to prolong battery lifespan; Data Hold function to freeze the current readout, easy to read and record data; Designed with flashlight illumination, suitable for sound date collection at night.
