The FT-2500 is an advanced tachometer which measures the rotational speed by the FFT calculation. The rotational speed is calculated from the frequency signal of light, magnetism, vibration or sound.

The FT-7200 Advanced Tachometer is an easy-to-use handheld digital tachometer offering high functions and performance. The use of FFT (Fast Fourier Transform) technology enables the FT-7200 to perform frequency analysis of rotation speed by using change of signal in sound, vibration or magnetic flux from rotating machines such as a motor or the like. Selection from 5 kinds of measurement modes allows it to calculate and display rotation speed of any complex waveform signals from a sound level meter or an accelerometer accurately by extracting the exact frequency component.  

The CT-6520B Universal Engine Tachometer accepts a large array of revolution detectors to meet different measurement conditions such as location of detector, type of an engine and so on. This tachometer uses a multiplier circuit to both reduce the measurement time and improve measurement accuracy. Analog, digital and pulse outputs are provided as standard.

The MP-981 is a magneto-type detector using a hall element which is suitable for revolution (r/min) measurement from low speed to high speed. Magneto-type detectors use an internal hall element, a permanent magnet, DC amplifier, and voltage regulator and respond to flux, so that a rectangular wave form is derivable from much lower speed all the way though high speed. In addition, a signal indicator is provided in spite of the detector`s compact design, making verification of operation and mounting position possible. Meanwhile, the AP-981 is the water and acid proof type, which conforms to Class ` of JIS C0920.

The GE-1200 makes taking rpm measurements on a 4- cycle diesel engine easy. Safe measurements with an accuracy of ± 1 rpm are as simple as clamping the detector to the fuel injection pipe.

Introducing our new tachometer with a clear display and ability to add functions separately and easily. The fluorescent display tube of TM-3100 series greatly improves stability and readability instead of using LED as old models.

The LG-916 is a reflective-type photoelectric rotation detector that employs an optical fiber at it`s tip. A pulse modulation method has been used for the light projection source, and the detector has been designed to be virtually unaffected by ambient light. Discontinued and upgraded with the longer range LG-9200.

Digital Linear gauge discontinued and possible replacements are the EG-225, GS-3813 and GS-3830.
