Time averaged sound level LAeq LAFmax, LAFmin, LASmax , LASmin สินค้าจากฝรั่งเศษ พร้อม Certificate of Calibration

DB 100 sound level meter is reliable, easy to use and in accordance with metrology requirements.
DB100 can measure :
-Sound-pressure level
-Time averaged or equivalent continuous sound pressure level

Sound-pressure level L_A as per two weighting times FAST or SLOW
To be used for stable or slightly fluctuating sound sources.
Sound-pressure level (L_A) unit is dBA and LAmax and L_Amin values are saved.
Time averaged sound level L_Aeq
To be used for fluctuating sound sources. Time averaged sound level (L_Aeq) unit is dBA with a programmable integration time in minutes and seconds.

Measured parameters : L_A et L_Aeq
Other displayed parameters : L_AFmax, L_AFmin, L_ASmax, L_ASmin
Frequency weighting : A
Measuring range : 30-130 dB
Resolution : 0,1 dB
