Product outline

F377A is a digital indicator integrated with a voltage / current output type sensor that can display physical quantities such as pressure, load and torque in waveforms. It can be connected to the voltage of ±10 V and the current of ±20 mA. It is able to visually capture in waveforms the fluctuations in physical quantities which are difficult to capture by only numerical values.
With a maximum 2000 times per second for high-speed processing, it is also ideal for narrow value fluctuations and comes equipped with a HI/LO limit comparison function, various hold functions and judgment function.
F377A is the best digital indicator for graders and testers used in results judgment of assembling work and auto machining.
