Sound Level Meter DB-100

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 LA as per two weighting times FAST or SLOW To be used for stable or slightly fluctuating sound sources. Sound-pressure level ( LA ) unit is dBA and LAmax and LAminvalues are saved.
