Used to measure the sound level of the environment such as factories, workshops, schools, residential buildings, office areas, traffic roads, audio and other occasions of the sound level.
Large range from 30dB to 130dB; high accuracy of ±1.5dB(94dB@1KHz); and high resolution of 0.1dB.
[Fast/Slow Time Weighting]
Select FAST(125ms) to capture noise peaks and noises that occur very quickly; select the SLOW(1sec) response to monitor a sound source that has a consistent noise level or to average quickly changing levels.
Press the Data Hold button to freeze the displayed reading; auto/manual range for accurate measurement; unit conversion between dB and SONE is available.
Measures 7.59*2.36*1.14in and weighs 6.13oz, featuring compact and lightweight; and LCD HD color screen ensures clear visibility even in low-light area.
*Batteries are not included.
*Wind blowing across the microphone increases the noise measurement. Use the supplied windscreen to cover the microphone when applicable.
*Calibrate the instrument before each use if possible. Especially if the meter has not been used for a long period of time.
*Do not store or operate the instrument in areas of high temperature or humidity.
*Keep meter and microphone dry.
*Avoid severe vibration.
*Remove the battery when the meter is to be stored for long periods of time.
*A Frequency Weighting: The frequency response of the meter is similar to the response of the human ear. A weighting is commonly used for environmental or hearing conservation programs such as OSHA regulatory testing and noise ordinance law enforcement. Most noise measurements are performed using A weighting and FAST Response.
