Product Description
HT622B Digital Sound Level Noise Voice Meter Volume Measuring Instrument Decibel Monitor Logger Diagnostic-Tool Detector Audio Tester
With A / C weighted measurement range from 30dB to 130dB, this portable sound level meter can be applied for noise engineering, product quality control, health prevention and control, etc.
* Batteries are not included if ship by Air.
* 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.
[Wide Application] 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.
