Hioki FT3432-20 - Sound Level Meter

Convenient measurement of sound levels from electrical equipment and machinery

Sound meters are used to measure sound and noise levels in a variety of settings, including at electrical worksites, in the vicinity of fire alarms and loud machinery, and at plants, schools, and airports. They are also essential equipment for electrical work, a field where HIOKI has been leveraging its specialized knowledge to sell innovative products for more than 10 years. Development of the FT3432 was spurred on by market demand for a sound meter that was small, light, and easy to use in the field.

Because the SOUND LEVEL METER FT3432 is the industry’s smallest sound level meter, it is ideally suited to use in on-site measurement. Its compact body houses an extensive selection of measurement functionality designed to facilitate sound research, and compliance with the JIS C1509-2 Class 2 and IEC 61672-1 Class 2 standards ensures high measurement precision. Additionally, a verified model is available for transaction and certification use.

The FT3432 packs all the functionality you need in the field into a small, lightweight body.

Advanced Features

• Compliance as an approved normal sound meter for transaction and certification use
  • Sound meters are considered specified measuring instruments under Japan’s Measurement Act, necessitating that any sound meter used in transactions1 or for certification purposes2 be subject to verification testing. A verified model of the SOUND METER FT3432 is available.
  • An inexpensive model that has not been subject to the verification process is also available for users who do not require an instrument certified for use in transactions or certification applications.
• Terminology
  • Under the Measurement Act, the term “transactions” refers to “any act committed in the course of business, whether with or without consideration, for the purpose of supplying goods or services.”
  • Under the Measurement Act, the term “certifications” refers to the act of representing “to others publicly or in the course of business that a certain fact is true” (examples include body measurements taken at hospitals and sound surveys taken of a facility’s environment).
• Lightweight design and industry’s smallest size
  • The FT3432 is an extremely compact, lightweight sound meter designed for on-site measurement use. Just 120 millimeters in height and 105 grams in weight, it can easily be used to take readings with a single hand. A silicon cover and hand strap protect the instrument in the event it is dropped, and an included carrying case makes it easy to carry.
• Simple operation
  • Three buttons make it easy to switch among the instrument’s sound measurement functions.

• Electrical equipment (measuring noise generated by high-voltage electrical transformers, the volume of alarms, etc.)
• Fire safety equipment (measuring the volume of alarms, etc.)
• Machinery (detecting abnormal sounds, performing factory shipping inspections, etc.)
• Transport (measuring noise inside automobile interiors or train cars)
• Factories (measuring noise produced by factories, performing shipping inspections, etc.)
• Schools (measuring noise in classrooms)
