The Hioki FT3405 and FT3406 are portable, contactless digital tachometers that use reflected visible spectrum light to measure the speed of a rotating object to which reflective tape has been affixed. The instruments can also be used as a contact-type tachometer by attaching the Z5003 Contact Adapter. Key Features • Convenient analog and pulse output functions • Dust-proof construction and drop-proof to 1 meter • Wide measurement range of 0.5000 r/s (30.00 r/min) to 99990 r/min • Contact style testing available with optional contact adapter • Convenient analog and pulse output functions (FT3406 only) • Optional AC Adapter (FT3406 only)
Contactless measurement
Contactless performance ensures safety and peace of mind when measuring rotating objects that are recessed inside equipment or whose movement poses a hazard. Simply apply reflective tape to the object being measured, point the instrument at the tape, and press the button. The instrument can detect rotation from a distance of 500 mm while illuminating the measurement location with red light to help you aim it precisely. The HOLD key turns red following accurate measurement and the instrument beeps, so there’s no need to worry about whether the target object has been measured properly.
Durable construction built to withstand being dropped and getting dirty
The FT3405/FT3406 is built to withstand being dropped, so it won’t break easily, even if it slips and falls out of your hands. IP50 dust-proof structure makes the Tacho HiTesters tough against the dirt and dust that are unavoidable in field environments. *IP codes indicate water and dust resistance standards defined by the International Electrotechnical Commission (IEC). They consist of two digits, the first of which indicates dust protection and the second water protection. An IP code of 50 has dust protection of 5, indicating that the device in question provides sufficient protection against dust to avoid interference with device operation and safety.
Flexibility to accommodate different use cases
Thanks to a grip that’s designed to fit snugly in the hand, the instrument can be held and operated single-handedly. There’s also a tripod mounting hole so that the instrument can be secured on a tripod during measurement. This feature is convenient when you need to perform measurement over an extended period of time.
Ability to track changes with analog and pulse output of RPM
Measure signal variations with a waveform recorder or data logger by using the FT3406’s analog output or pulse output functions. Use a multi-channel logger in combination with input from other types of sensors, or a multi-channel recorder to simultaneously measure voltage and current.
