Convenient Measurement of Sound Levels from Electrical Equipment and Machinery


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.

Key Features

  • Simple operation, no range switching needed
  • Compact, lightweight design for easy one-handed operation
  • 30 dB to 137 dB
  • Analog output
