ATP MT-911A Mini Sound Level Meter with Temperature
ATP MT-911A Mini Sound Level Meter with Temperature combines sound level measurement and ambient temperature measurement in one compact instrument. It measures sound levels from 35 to 135 dB with 0.1 dB resolution and uses fixed A frequency weighting. Fast and Slow time weighting allow the meter to suit changing or steady sound levels during routine checks.
A bright 30 mm colour LCD presents large digits and function indicators for clear viewing, while the backlight helps in low-light work areas. Readings update approximately every 300 ms, allowing sound changes to be followed as they occur. Data hold can freeze the displayed value, while minimum and maximum capture records the lowest and highest readings during a test.
Designed for mobile surveys, the ATP MT-911A Mini Sound Level Meter with Temperature weighs 73 g and measures 144 x 56 x 31 mm. A supplied wind muffler helps reduce gust noise during outdoor measurements or work near vents. Three AAA alkaline batteries power the meter, with a low battery indicator and a user-selectable automatic power-off function for practical day-to-day use.
