LCD Touch Panel Display Digital Indicator F370&F371


It is able to visually capture in waveforms the fluctuations in physical quantities which are difficult to capture by only numerical values.

A state-of-the-art digital indicator that controls measurement by amplifying and performing high-speed digital processing of recognizable signals received from a strain gauge sensor that measures pressure, load or torque. With utilization of liquid crystal touch panel display, visibility and operability of waveform display and others are greatly improved. Through its ample 20 types of waveform hold function, it is the best digital indicator for graders and testers used in results judgment of assembling work and auto machining.
