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 , product quality control, and control
Features:
【A/C Weighted Measurement】When measuring the sound level felt by human beings, 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, 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 , 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/, which is suitable for measuring the sound level in real in general environment; The Slow-Weighting mode uses a 1s/ constant, which is suitable for environmental measurements with relatively large changes in noise levels.
【Compact and Lightweight】 using composite material injection molding process, -drop structure design, not only solid wear-resistant, but also beautiful and comfortable to hold; Slim and lightweight, doesn't take 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 LCD screen with a resolution of 0.1 , clear and beautiful; A sound level bar is displayed on the screen, and it's equipped with a sound level indicator as dual visual alerts; Digital display, with advantages of -interference performance and saving. A indicator will appear on the screen when the is low to remind the user to replace the in .
【Versatile Uses】MAX hold function to lock the maximum value; Auto off after 15 minutes inactivity to prolong 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.
