Hioki FT3432 SOUND LEVEL METER
The Hioki FT3432 sound level meter is used in noise management by facilitating the measurement of noise in factories and schools, near machinery, etc., to ensure a more comfortable environment. Small enough to fit in a pocket and weighing just 105 g, the instrument measures sound level, equivalent continuous sound level, sound exposure level, maximum sound level, and C-weighted peak sound level.
