Competent in measuring and recording speeds of rotational, linear and surface as well as total length, Shimpo Instruments’ DT-105A-S12 Contact Tachometer with a 12” Contact Wheel is part of their DT-100A series of tachometers. The DT-105A-S12 is equipped with a list of advanced features and functions that are still user friendly: retrieval of the last, maximum and minimum values, memory storage, length functions and the quick adjustment unit’s knob.
Using the most advanced microprocessor technology, the battery operated DT-105A-S12 delivers excellent accuracy in measuring speed and length by way of its 12” contact wheel. Rotating at a slower rate than the standard 6” wheel, the 12” wheel permits dependable and safe recording of high speeds. Offering a LCD display and quality performance, the DT-105A-S12 Contact Tachometer has made Shimpo Instruments a paradigm in the industry.
