Specification BatteriesIncluded : 1 BatteriesRequired : 1 Brand : Weytoll BulletPoint1 : 【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. BulletPoint10 : 【Low power indicator】 When the battery voltage decreases to a certain extent, the battery symbol in the upper right corner of the display will light up. In this case, the battery should be replaced. BulletPoint2 : 【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, o system, automobile, school, office, factory. BulletPoint3 : 【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. BulletPoint4 : 【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. BulletPoint5 : 【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 power saving. A battery indicator will appear on the screen when the battery is low to remind the user to replace the batteries in time. BulletPoint6 : 【Result Hold】The measurement result (HOLD) function;Press the HOLD key to hold the measured sound level value BulletPoint7 : 【Sound level OVER or UNDER indicates】If the display displays "UNDER" or "OVER" characters, the sound level is lower than 30dB or higher than 130dB. BulletPoint8 : 【LCD with backlight】After power-on, the backlight will automatically light up and turn off after 30 seconds. Press the backlight button to turn on the backlight. BulletPoint9 : 【Automatic SHUTDOWN】3 minutes after the stop button, the meter will automatically shut down to save power.
