Digital Tachometer TM-4000 Series
A new standard for tachometers that integrates four models.
Revamping the lineup of digital tachometers. The TM-3100 series has been redesigned, giving birth to the new digital tachometer "TM-4000 series," which integrates a multifunctional tachometer, reversible counter, and passage time/passage speed meter. While inheriting the functions and performance of the previous models, it pursues high precision and high responsiveness. Users can select the input format according to the connected external devices and sensors, allowing for customization by combining various functions such as analog output, comparator output, and DC power supply. The TM-4000 series meets the diverse needs of rotational speed measurement and supports the realization of DX and smart factory initiatives.
