Product Description
HT622B Digital Sound Level Noise Voice Meter Volume Measuring Instrument Decibel Monitor Logger Diagnostic-Tool Detector Audio Tester
Habotest has over hundred various patents and set an independent innovation goal of reaching more than 100 authorized patents each year. After 20 years industry experience in research and development, Habotest standardized its management and quality systems, obtaining ISO9001-2008 and ISO/TS16949, CE, IEC safety standards and introducing financial ERP systems.
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.
[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.
Note:
* 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.
